Two options. Either the alternator is bad (voltage reg), or the computer is no good. Turn the head lights on (at night). If thy flicker, like high beams, then the computer is fried. C.E.

Can a bad alternator cause a battery to be unchargable?

Yes, it can ruin the battery by overcharging it. If you are reading between 13.5 to 15.5 volts at the battery with the engine idling then more than likely the alternator is good and you battery has a dead cell. A fully charged battery will read 12.6 volts with the engine not running.

Can you add miles to your car by idling?

You can add engine wear but the reading on the odometer will not change since the sensor for the odometer is located at the output end of the transmission or transaxle, and therefore only gives a reading when the vehicle is moving (or when the wheels are spinning, if you are on ice or up on a hoist). So, no, you will not add mileage by idling.

Low oil pressure reading when idling for a 1986 fiero?

A low oil pressure reading when idling for a 1986 Fiero is normal. As long as the oil pressure goes back to normal when the car is being driven, there should be no problem. If it is not, then the oil pressure sensor or the oil sending unit should be looked at.

Can an alternator that has a built in voltage regulator show good when the regulator is bad?

If the regulator is bad, the alternator would have a low charge or a high charge or no charge at all. With a good battery that is fully charged (12.68 volts) and the engine warmed up and idling with no accessories on, you should get a voltage reading at the battery of 14.2 v (plus or minus .2 v).

Bad Alternator and have your battery checked for bad cells

Why new battery and alternator won't hold a charge when car is running?

The alternator does not hold a charge. It charges the battery. If it will not charge the battery then either the alternator is defective, battery is defective, or the connections are corroded or loose. You should read 13.5 to 15.5 volts at the battery with the engine idling. Check it with a DC volt meter. If you get less the alternator is defective. If you get much more the voltage regulator is defective.

How hot is normal for a new alternator to get when idling for an hour after replacing it and the battery on a 1993 Buick Skylark?

They will run somewhat hot while charging; if you put your battery in discharged however, that makes the alternator work much harder. A alternators job is to maintain the charge in a battery not to charge a discharged battery.Keep a eye on it, it will probably be OK once the the battery is topped off.
