My advice is to charge the battery with a battery charger before starting the engine. You will be putting a heavy load on the alternator if you allow it to charge a dead battery. This could damage the alternator.

Will battery recharge after bad alernator is replaced?

An alternator is designed to keep a fully charged battery at peak level. It is not designed to charge a dead battery. Installing a new alternator on a car with a dead battery can in some cases ruin the new alternator. Fully charge the dead battery before starting the engine.


88 caddilac deville alternator only givein you 13.3 with the battery help please not gettin all power?

Be sure the battery is fully charged before you start. A fully charged battery should read 12.68 Volts. If the battery is very low when you check the alternator output it will not give you an accurate reading.


Battery light stays on in your Chevy silverado 2005?

test the voltage on the battery first, then on the alternator. If its good then it could just be the diode in the alternator. I would suggest you replace it becuase eventually your alternator will die and the battery will not get charged leaving you stranded somewhere. It is possible to just be a battery but you wont know unless you have the battery tested. check the voltage on the battery and the alternator before you do anything else.


Should your car start right after changing the alternator?

If the battery is fully charged and the starter is working properly it will turn over and start. The alternators sole purpose is to supply voltage to the vehicle and battery when the engine is running. When the engine is not running the alternator has nothing to do with starting the engine. If the alternator went bad and the battery was discharged then you will have to charge the battery before it will be able to start the engine. Do not jump start the engine with a dead battery if you can avoid it. This puts a strain on the alternator trying to recharge a dead battery and can damage the alternator, even a new one.


What charges the battery on a Harley Davidson?

Modern Harleys have an alternator that not only keeps the battery charged but also provides power for the lights, horn, etc. It works in conjunction with the voltage regulator which controls how much of the alternator's power goes to the battery and how much goes to accessories. Harley Big Twins built before 1970 used a generator instead of an alternator.


Why isn't the rebuilt alternator charging that I put in my 1996 Ford Taurus GL?

Does your Bat warning light stay on or if you have a Voltage gauge what does it read. Was your battery fully charged before you installed your new alternator? Remove alternator and have it tested to besure that it was indeed the problem.


How long should jump-leads be left on a dead battery before it will be fully charged?

Recharging a dead battery by using jumper cables connected to another vehicle is a very bad idea. You are overworking the alternator on the donor vehicle and can very well destroy that alternator. Recharge a dead battery with a battery charger and never with another vehicle.

To replace the alternator on a 1999 Suzuki Esteem, first disconnect the negative battery cable to ensure safety.

Do you fit a car battery if the voltage is under 12.4v?

A fully charged battery will read 12.6 volts. A battery reading 12.4 volts is 75% charged. 12.2 volts = 50% charge, 12.0 = 25% charge. You should use a battery charger to charge any battery reading less than 12.4 volts before installing it on the vehicle.


How can you tell if it is an alternator problem or just a dead battery?

generally if you hook up a multi-meter to the battery and start the engine it should read 13.5 or 14 volts, when you turn on headlights and other accessories the alternator should keep the battery charged up to at least 12 volts, you can also just check the battery to see how many volts it's putting out before you start the vehicle


I just changed the battery in my car and put the battery cables on backwards now the battery won't charge I tried a different battery and still wont work. Could I have damaged the alternator?

when you reverse connect a battery there is a good chance you will blow the main fuse this will protect the car from more damage but usually stops the battery for been charged as well... check and change the main fuse or fuseable link The alternator probably already was bad before you put the battery in.
