Finding Alternator Faults

Checking the alternator to make sure it is charging properly will save a lot problems in the future.The light on the dashboard known as the battery light will let you know if the battery is being charged or not.If your car is fitted with an alternator and not a dynamo, then this light should work for most cars, in exactly the same way.Once you turn the ignition key to the "ignition on" position, the ignition light should come on.Once the engine has started running the light should go out fully or at least as soon as you get above an idling speed.If the light does not come on at all before the idle speed or comes on after the idle speed, then there is a fault in the charging system.If the problem is the light does not come on at all and the wire is connected, the most likely cause is the bulb may have blown in the dashboard.The bulb is normally behind the instrument cluster so may not be that easy to get to.If the ignition light comes on after the idling speed, then there could be more than one problem.The first thing to establish is if the battery itself is suitable for charging, for example, if the battery is so dead that it cannot take the charge this could be the reason.The gravity of the electrodes in each cell will have to be checked with a battery hydrometer.This is particularly important for batteries that have been standing around for a long time.Then check the battery is connected properly with good connections and a smear of Vaseline to prevent any corrosion.If the battery is suitable for charging and connected properly, then check the tension of the drive belt to make sure it is not slipping.If that looks fine, then test the alternator is working by putting a multimeter across the battery whilst a friend revs the engine check to see if the volts raise from 12 volts to around 14volts.If the volts do not rise, you will have to investigate further.Most connections to the alternator are done via a multi-plug.Check first to make sure the plug has not come loose.If it has, push it back in and take the reading again.If the volts are still not rising, then remove the multi-plug and with the multimeter put the negative wire of the multimeter to the earth of the car and then test each connection of the multi-plug with the positive probe.If you see 12-14 volts on each connector, then the alternator will be deemed to be at fault.Normally at that stage an auto electrician should be able to tell you if it is just new brushes that are needed or a replacement alternator.

Batteries - Maintenance & Testing

Battery Charging.A.Ensuring correct polarity, connect battery charger.B.The battery should be charged at normal bench charge rate.Battery is fully charged when the charging voltage and electrolyte level show no increase over a period of at least 2 hours.Minimum charging is 4 hours.The charge time must be extended on a pro-rata basis if the only available current is lower than that specified.C.Acid temperature must not exceed 50°C during charging.If necessary, interrupt or decrease charging current.D.Check that specific gravity on all cells is 1.280 (0.010 when fully charged).E.Now, replace the vent plug and check electrolyte levels in all cells two hours after charging.Using distilled water, adjust to 15 mm above the plates or to the "MAX" line, if necessary.Visual Checks.Look out for powder forming around the battery terminals or bases of batteries and for leaks.This can lead to corrosion.Look out for any damage or knocks to the batteries.Battery Maintenance.A.Battery tops and terminals must be kept clean.B.Use petroleum jelly or similar to coat terminals and connections sparingly.C.NEVER overtighten terminals, but keep them tight.D.Electrolyte should be 3 mm (1/8") to 6 mm (1/4") above the top of the plates.Check regularly.Use only distilled water or chemically pure water if topping up is required.E.Ensure the alternator/generator belt is tensioned to manufacturer's recommendations.Check it regularly.Also check regularly for signs of wear.Battery Testing.Always make a visual examination before testing batteries with instruments.1.Corroded terminals - a white powdery substance around post connections which may prevent battery charging.2.Check that all cells contain electrolyte.A dry cell indicates a cracked casing.3.Check for loose terminals and any other external damage.Hydrometer Testing Use a hydrometer to establish the specific gravity of the sulphuric acid in the battery, and as a result of the state of charge.Method.1.Do not add distilled water.2.Keep the barrel upright, draw up enough electrolyte from each cell in turn to allow the float to ride free.If necessary, tilt the battery to obtain sufficient electrolyte.Read off at eye level.1.270 to 1.280 S G Full Charge 1.220 to 1.230 S G Half Charge 1.150 to 1.220 S G Discharged.The readings from all cells should be within 0.030 points.If the variance is greater, then it is likely that the battery needs replacing.If all cells are consistently low, the battery may still be serviceable but we advise battery replacement as quickly as possible.Diesel Generator Batteries.Diesel generators are rarely thought of when mentioning power protection systems and batteries but a battery is a key component in any standby generator.The battery is required to start-up the generator as soon as the mains power fails and without it, the generator would be pointless.

How to Refurbish Industrial Batteries

Industrial batteries are made using thick plates so that they can offer prolonged usage time.Sometimes, their performance may be reduced and this calls for them to be refurbished.Industrial batteries are much bigger than SLI, marine and automotive batteries.Refurbishing industrial batteries allow them to restore their capacity to store charge for longer periods of time.Below are the steps that you should take to refurbish an underperforming industrial battery.A forklift is needed to lift the battery to a concrete wash.A forklift is used because these batteries are very heavy some of which weighing as much as 20,000 pounds.When in the concrete wash, record the voltage readings in order to calculate the amount of current that is flowing between its terminals.If the voltage reading is more than 20 volts, you should further discharge it till you get a value slightly below 20 volts.After discharging the battery, the next step is cleaning its terminals.Sprinkle the battery top and the terminals using baking soda and then wet using fresh water.Use a wire brush to scrub the top and terminals to remove all the corrosion that may be present.Use fresh running water to wash the top and the terminal to ensure that it is very clean.The next step aims at measuring the acidity of the battery acid.Remove all the caps from the battery top and use a hydrometer to measure this acidity from each of the cells.Battery water should have a 30% sulfuric acid and 70% water.Record the concentration from each cell and see how they deviate from the normal concentration.The deviation obtained from each cell should aid you in establishing the amount of water or acid that should be added to each cell to restore the required concentration.Adjust these concentrations while using the hydrometer to measure the concentration.When you are satisfied that the required concentration has been reached, connect the battery to the charger and allow it to be charged for about 8 hours.After 8 hours the battery should be fully charged.Use a voltmeter to measure the voltmeter reading and record it.If the battery does not attain the expected voltage, it may mean that there is something wrong with some cells in the battery.Use the hydrometer again to measure the acid concentration from each battery hole.You will observe that there will be some cells whose will have changed and therefore you need to readjust them by adding distilled water or sulfuric acid.Repeat this process until all the parameters are correct.If after all these adjustments you realize that there are still those cells that are unable to hold charge, then you should go ahead to replace these cells because they are destroyed.It is important to note that refurbishing an industrial battery should be done by a professional or somebody who have a great experience in handling this type of batteries.This is because industrial batteries hold a very high voltage which if not handled correctly could be very dangerous.

The Best Auto Battery Chargers

If your generator isn't exercising as it should, you may have a dead battery.Before you toss it out, check to see if it can be recharged.There are different types of charges.The most common are a manual charger, trickle, and a pulse charger - just to name a few.And there are different types of batteries and they can affect the charge outcome.Different Types Of Batteries.According to Wikipedia, "A battery charger is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it." Whether a battery takes a charge depends upon the size and the type of battery being charged.There are 3 main types..Lead acid.Nickel-based NiCd.Lithium-ion.Air glass mat.Different Types of Chargers.Many people use an automatic charger.When you try to charge up a battery and you are using a digital charger, will it work? A digital instrument will tell you if the battery falls below the 80%.Many people say it can't be recharged if it falls that low but it is not necessarily true.Some batteries can be rejuvenated and just need a charge to start, depending upon the age of the battery.One customer had a problem with a generator.His battery charger indicated it was dead.He was using an automatic charger but you can have problems with an automatic charger too, if you battery falls below 80%.A battery has to have a certain amount of charge for it to start charging.You need to understand how to check batteries.Auto parts stores will tell you that your battery doesn't have enough voltage so they can't charge it.What I recommend is to keep putting low voltage back in to your battery and see if it will come back up.A trickle charger may not bring it up at all because a trickle charger needs a certain amount of voltage for it to recharge.Sometimes you have to have a manual charger in place of an automatic because an automatic has to have voltage to start it.Problems With Battery Chargers.Charger might tell you that your battery is dead when it still could be a good battery and be fully charged.Chargers can be deceiving.Problems can occur when trying to charge you battery.Chargers go bad.Battery dropped below their 80% level.Dead cell.If it's a newer battery, it may come back up if it didn't kill a cell.A hydrometer is a tool that will test for a dead cell by checking the electrolytes.With sealed batteries, you can't open them to tell.If your automatic charger says it's dead, then try and put a little charge back in to it, manually and slowly.But be careful! You don't know the condition of the battery.It's dangerous.You could blow a battery apart.Conclusion.Batteries can get complicated.Automatic chargers may not recharge your battery.You may need to use a manual charger to bring up your battery.Another opting is to bring it to an auto parts dealer and have them charge it for you.They use sophisticated equipment.Some people are wasting money and filling up the garbage dumps with batteries because they are incorrectly charging them.Don't waste money.Make sure your batteries are completely dead before replacing them.

Battery Reconditioning For Car Batteries - Essential Tips

In today's tough economic times everyone seems to be looking for ways to save up on money or make money When it comes to taking care of your car, a great way to save money (or even make money on the side) is through battery reconditioning for car batteries.Rechargeable batteries are quite expensive, and instead of throwing them out and buying a new one you can have them reconditioned so that you can use them again.Battery reconditioning can be done right at home, as long as you know what to do and have the right instructions to follow.Here are some tips to follow in reconditioning your car batteries to make them work like brand new.Tip 1. Check if the battery can still be reconditioned Not all batteries can be reconditioned, so you have to check if your car battery still holds any charge.If the battery won't hold even just a little charge, then reconditioning it is impossible.Always recondition a battery when you feel that it's already 'dying' - not when it's already 'dead'.Tip 2. Get all materials ready You will need to gather all necessary materials such as a nanopulser (or desulfator), de-ionized water, multimeter and hydrometer.Tip 3. Start The Reconditioning Process The reconditioning process is quite easy.You will simply need to hook up a nanopulser to your battery.After that, all you have to do is wait for a couple of days.Then you measure the voltage to see if the battery's holding any charge.Then you hook it up again for a couple of days and repeat the process over and over until the batter holds more than 14 volts.Tip 4. Read Up and Do Some Research If you have zero knowledge in battery reconditioning for car batteries this does not mean that you cannot do the process yourself.A little reading and some research beforehand may help.You may also want to make use of a helpful guide which can walk you through the whole battery reconditioning process.Tip 5. Safety First Remember that reconditioning car batteries means that you're dealing with power - so think safety first.Remove any jewelry that you are wearing and make sure children aren't around when you're working.Tip 6. Be Prepared to Wait The whole reconditioning process can last as much as two weeks, so make sure you have a spare battery to use for your car.The process may take a long time, but the savings that you make out of it makes the whole thing worth the time and effort.Remember that reconditioning batteries may take up some time, but if you keep on doing this to your car batteries you will certainly end up saving thousands of dollars.In fact, once you get the hang of it, you can even offer to recondition batteries of friends and other people as a side business.It doesn't take up much of your time, and you earn extra money on the side as well.

Winter RV Battery Storage

The two most common causes for RV battery failure are undercharging and overcharging.Undercharging is a result of batteries being repeatedly discharged and not fully recharged between cycles.If a battery is not recharged the sulfate material that attaches to the discharged portions of the plates begins to harden into crystals.Over time this sulfate cannot be converted back into active plate material and the battery is ruined.This also occurs when a battery remains discharged for an extended period of time, like during storage.Sulfation is the number one cause of battery failure.The second leading cause of battery failure is overcharging.Overcharging batteries results in severe water loss and plate corrosion.With that said let's look at how to properly store your RV batteries.Before we talk about storing the batteries we need to talk about battery safety.Lead acid batteries contain sulfuric acid which is extremely corrosive and can cause severe burns or even blindness.And the hydrogen gas that batteries produce when they're charging is very explosive.When you work around batteries you need to wear goggles and gloves, remove all jewelry and do not smoke or use any open flames.Caution. If you accidentally get battery acid on your skin, flush it with lots of water and if it gets in your eyes flush with low pressure water for 15 minutes and call a doctor.When you put the RV in long term storage it's a good idea to remove the batteries and put them in storage too.This is quite simple to do.The first thing we want to do is visually inspect the batteries for any obvious damage.Any fluid on or around the battery may be an indication that electrolyte is leaking from the battery.A damaged or leaking battery should be replaced immediately.Whenever you remove any battery always remember to remove the negative terminal or cable first, and then the positive cable.Battery Tip. When you remove a battery turn off the ignition switch, all electrical switches, and any battery disconnect switches before you disconnect the battery cables.Whenever you remove any battery cables label them first so you remember how they go back on the battery.When you reinstall the battery do it in the reverse order.Install the positive cable first and then the negative cable.Clean the batteries with a 50/50 mixture of baking soda and water if necessary, i.E.Use one pound of baking soda to one gallon of water.Now you can check the electrolyte level in each cell and add distilled water if necessary.The minimum level required is at the top of the plates.If it's below the plates add enough distilled water to cover the plates before you charge the battery.Test the battery state of charge with a voltmeter or hydrometer and charge any batteries that are at or below 80%.An 80% charge is approximately 12.5 volts for a 12 volt battery and 6.25 volts for a 6 volt battery.Lead sulfation starts when a battery state of charge drops below 80%.After charging the batteries check and fill each cell to 1/8 inch below the fill well with distilled water.Overfilling cells will cause battery acid to overflow.Caution. Batteries should only be charged in a well ventilated area and keep any sparks and open flames away from a battery being charged.Check the electrolyte levels before and after charging batteries.A discharged or partially charged battery will freeze much faster than a charged battery.Store the batteries in a cool dry place but not where they could freeze.Batteries in storage will loose a percentage of current through internal leakage.It's not uncommon for a battery to discharge up to 10% a month when it is being stored.Cold temperatures slow this natural discharge process down and warmer temperatures speed the process up.Test the stored battery state of charge every month and charge batteries that are at or below an 80% state of charge.Completely charge the batteries before re-installing them next spring.For optimum performance you can equalize the batteries after they are fully charged.An equalizing charge is an increase in charging voltage similar to a bulk charge to convert any crystallized lead sulfate back into its original components.If you decide to leave the batteries in the RV while it is in storage remember to check the state of charge monthly and charge any batteries at or below an 80% charge.Some RV converter multi-stage chargers and aftermarket chargers are designed to maintain a float charge on the battery without removing the batteries from the RV.Remember, for the converter charger to work the RV will need to be plugged in to electricity.For more information on RV batteries check out our Deep Cycle Battery Care & Maintenance DVD.Happy Camping,.Mark Polk.Copyright 2007 by Mark J.Polk, owner of RV Education 101.

Battery life depends greatly on maintenance.The life span of deep cycle RV batteries is often 5 to 10 years, depending on use and maintenance.Well-maintained units and banks may last for 15 years or more just by following a few simple steps.Sink Some Money into Your Cell Bank.Most things we purchase follow the adage, "you get what you pay for," and RV batteries are no different.High quality units will likely run $100 to $600 depending on the size.A mid-range $400 product that lasts 15 years averages out to about $27 per year.Don't be afraid to put money into your investment.Avoid More than 3 Parallel Strings.Keep your cell bank short and simple.No more than three parallel strings are advisable at any given time.Fewer cells reduce the possibility of random defects and makes maintenance much easier.Prevent Corrosion.Corrosion is one of the worst enemies.Corrosion causes a hazardous situation and reduces the effectiveness of the power source.One of the best preventative techniques is to apply a thin layer of petroleum jelly to the terminals.Vaseline does not inhibit electric current, but protects terminals very well.Moderate the Temperature.Keep the temperature around 77 degrees Fahrenheit.Colder temperatures, around 30 degrees Fahrenheit, cause a 25percent deterioration of charge.Temperatures higher than 77 degrees Fahrenheit deteriorate even more quickly.Protect your power units from extreme temperatures in either direction.Low Voltage Disconnect.Exhausting a unit of all charge causes immediate damage and reduces the life expectancy.This damage is not reversible.The unit may temporarily charge again, but it will never hold a charge as well as a well-cared-for battery.Use a low voltage disconnects to prevent complete depletion of charge on all deep cycle style units.Fully Charge Every Three Weeks.Fully charging deep cycle RV batteries once every three weeks reduces internal corrosion.Charging also helps insure equalization by allowing weaker ones to rely on others.System Monitor.Monitoring the status of the cell bank is absolutely necessary to the proper maintenance of the unit.They monitor the state of charge, voltage, current and record amp hours.Understanding these readings will prolong the life of your product.Hydrometer.A hydrometer is a device which helps determine if the cell bank is being charged to full.It will also show if any individual batteries or cells are falling behind.False readings may occur immediately after adding water, or if the temperature drops drastically.Longer Lasting RV Battery Banks.Remember that acid is a hazardous material.Always use safety equipment such as gloves and safety glasses.Keep a rugged plastic bottle filled with baking soda and water to rinse away accidental spills and to clean splatter from the tops of the battery.Maintenance is one of the primary staples of a long life.Some people choose to carry a motorcycle battery charger to maintain a light charge on RV batteries that may have problems keeping a charge.Keep stored units at a consistent temperature and consider using a trickle charger.

Winter RV Battery Storage

The two most common causes for RV battery failure are undercharging and overcharging.Undercharging is a result of batteries being repeatedly discharged and not fully recharged between cycles.If a battery is not recharged the sulfate material that attaches to the discharged portions of the plates begins to harden into crystals.Over time this sulfate cannot be converted back into active plate material and the battery is ruined.This also occurs when a battery remains discharged for an extended period of time, like during storage.Sulfation is the number one cause of battery failure.The second leading cause of battery failure is overcharging.Overcharging batteries results in severe water loss and plate corrosion.With that said let's look at how to properly store your RV batteries.Before we talk about storing the batteries we need to talk about battery safety.Lead acid batteries contain sulfuric acid which is extremely corrosive and can cause severe burns or even blindness.And the hydrogen gas that batteries produce when they're charging is very explosive.When you work around batteries you need to wear goggles and gloves, remove all jewelry and do not smoke or use any open flames.Caution. If you accidentally get battery acid on your skin, flush it with lots of water and if it gets in your eyes flush with low pressure water for 15 minutes and call a doctor.When you put the RV in long term storage it's a good idea to remove the batteries and put them in storage too.This is quite simple to do.The first thing we want to do is visually inspect the batteries for any obvious damage.Any fluid on or around the battery may be an indication that electrolyte is leaking from the battery.A damaged or leaking battery should be replaced immediately.Whenever you remove any battery always remember to remove the negative terminal or cable first, and then the positive cable.Battery Tip. When you remove a battery turn off the ignition switch, all electrical switches, and any battery disconnect switches before you disconnect the battery cables.Whenever you remove any battery cables label them first so you remember how they go back on the battery.When you reinstall the battery do it in the reverse order.Install the positive cable first and then the negative cable.Clean the batteries with a 50/50 mixture of baking soda and water if necessary, i.E.Use one pound of baking soda to one gallon of water.Now you can check the electrolyte level in each cell and add distilled water if necessary.The minimum level required is at the top of the plates.If it's below the plates add enough distilled water to cover the plates before you charge the battery.Test the battery state of charge with a voltmeter or hydrometer and charge any batteries that are at or below 80%.An 80% charge is approximately 12.5 volts for a 12 volt battery and 6.25 volts for a 6 volt battery.Lead sulfation starts when a battery state of charge drops below 80%.After charging the batteries check and fill each cell to 1/8 inch below the fill well with distilled water.Overfilling cells will cause battery acid to overflow.Caution. Batteries should only be charged in a well ventilated area and keep any sparks and open flames away from a battery being charged.Check the electrolyte levels before and after charging batteries.A discharged or partially charged battery will freeze much faster than a charged battery.Store the batteries in a cool dry place but not where they could freeze.Batteries in storage will loose a percentage of current through internal leakage.It's not uncommon for a battery to discharge up to 10% a month when it is being stored.Cold temperatures slow this natural discharge process down and warmer temperatures speed the process up.Test the stored battery state of charge every month and charge batteries that are at or below an 80% state of charge.Completely charge the batteries before re-installing them next spring.For optimum performance you can equalize the batteries after they are fully charged.An equalizing charge is an increase in charging voltage similar to a bulk charge to convert any crystallized lead sulfate back into its original components.If you decide to leave the batteries in the RV while it is in storage remember to check the state of charge monthly and charge any batteries at or below an 80% charge.Some RV converter multi-stage chargers and aftermarket chargers are designed to maintain a float charge on the battery without removing the batteries from the RV.Remember, for the converter charger to work the RV will need to be plugged in to electricity.For more information on RV batteries check out our Deep Cycle Battery Care & Maintenance DVD.Happy Camping,.Mark Polk.Copyright 2007 by Mark J.Polk, owner of RV Education 101.

Car Batteries Maintenance Tips

A car battery's life can be shortened if not maintained correctly, to keep a battery in top condition here are some tips that may help.After all some batteries can be very expensive to replace, make sure you get your monies worth from them.Make sure the battery is fitted in the correct compartment of your vehicle, the battery tray should be clean and rust free and it should be a good level surface.The battery should be kept securely in this battery tray.Regularly clean the terminals and terminal connectors, if there is any signs of corrosion on the terminals then wash off with hot water and clean with a wire brush.Apply grease to the terminals and make this an important maintenance task.Make sure the electrolyte level is maintained at the correct level never overfill or underfill a car battery.Always use demineralized or distilled water and never use tap water or bottle water.If you have to replace a battery always disconnect the - negative terminal first and then the + positive, when the securing nut is slackened off always twist the terminal to release the hold and never just pull up.When fitting a new battery, apply a good quality grease first to the terminals and then connect the + positive first and then the - negative.If a battery has to be charged away from the car, then always charge in a well ventilated area, always away from any naked flame.It is best to use a trickle charge if possible, this will ensure the battery receives a good thorough charge.Problems with a vehicles charging system are not always the fault of a battery, other electrical items fitted to a car can cause problems.If you suspect you have a problem with a car battery, then it is always a good idea to have the battery checked first.A battery can be tested by either checking it's charging rate by using a multi meter or a hydrometer can be used to check the electrolyte in each cell or a discharge rate tool can be used.This is connected across both terminals and a heavy discharge is applied to the battery.The readings are monitored and a report on the battery condition is then given.A faulty starter motor can also have an effect on the vehicles cranking ability, if a starter is faulty it can often turn the engine over slowly or even not at all.These are symptoms very similar to a flat battery.Another simple test you can do yourself is to wait until it is a little dark and start your car engine.While facing a wall or fence turn your lights on.If you increase the speed of the engine while looking at the lights on the fence or wall ahead, you should see the lights get brighter.If the lights do get brighter it will show that the charging system of this vehicle is working and the alternator is not at fault.
