Clean both ends of both battery cables and make SURE there is a good ground cable between the engine and body. If this fails, take it to auto zone and have them check the alternator output.

Car losing power while driving?

something is wrong with the alternator, either it isn't working or it is not hooked up to the positive terminal on the battery. check your wires first before you assume you have a bad alternator, if it is hook up right and the wiers look fine then check to make sure the belt is not slipping on the alternator pully, if not then your going to need a new alternator and battery charge. because if your alternator is not working your car is getting all its power from the battery

Battery won't charge?

Either the battery is bad and won't accept a charge or the alternator is not putting a charge into the battery. Have the battery tested. You can hook up an inexpensive volt meter to the battery while the car is running. You should see from 13.5 to 14.5 volts if the alternator is working properly. If it is less than 13.5 volts then the alternator is not charging.

I recently installed a new stereo system into my car now my car sounds like my battery is weak is it my battery that I have to change or my alternator?

Check the battery with a vom meter while the engine is running. It should read about 14.5 volts and if so the alternator is working, than have the battery checked Now if the meter does not read 14.5 volts, have the battery, and the alternator checked. If they both check out okay, the problem is in the battery or the alternator circuit on the vehicle.

The new battery on your 1988 Cadillac Seville keeps losing it volts and stalling the carWhy?

It could be two things. As you know, the alternator charges the battery so it will not drain. If the alternator is not working properly to charge the battery, the battery will continuously drain. Have the alternator tested at your local Auto Parts store (NAPA or Advance Auto) If it is good, have the battery checked.

What does it mean when the battery light comes on?

Usually it means that the alternator isn't charging the battery. Batteries store electricity and the alternator uses energy from the engine to produce electrical energy for all of the devices in the vehicle and to recharge the battery. If the alternator isn't working the battery will eventually loose it's charge and you will not be able to start the vehicle.
