easy...all you have to do is to remove either one of the battery terminals,while the car is idling...if it dies,then it is not charging
If you question the condition of your alternator, drive to your local auto parts store and they will test the charging system for you at no cost.
If your battery doesn't hold a charge while running then your alternator is bad
let the car run and then pull the negative battery cable off. if the car stalls, the alternator is bad! do you know where the bank 1 o2 sensor 2 is?
it means your alternator is probably gone, and u need to replace it
if your alternator is gone or going your car will start and then eventually just stop running because your battery has gone dead. it typically will not make any sound when your engine is not running because of a dead battery.
Auto Zone will check your alternator for free...
water pump or seal gone bad
Alternator has gone or is going out.
Output of the alternator is controlled by the voltage regulator.
the light comes on when the alternator is bad or your regulator has gone bad. some regulators are built into the computer.
I have a 1997 ford expedition that the alternator is not charging the battery. Had the alternator tested and it was good the battery is new. Cant find the fuse for the alternator does anyone know where it is?
