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.

Symptoms of Ford Escape alternator failure?
unstable idling and battery indicator lights on.
Is it the battery or the alternator that is bad on a zx7r that shows 11.77 volts while idling at 3000?
Unless the battery is shorted or sulfated and will not take or hold a charge, most likely the alternator is bad
How do you tell if the alternator is outon a 1999 kia spehia?
A quick way to tell if there might be a problem with an alternator is to remove the positive side battery cable from the battery while the vehicle is idling. If the engine dies, odds are there is an alternator problem.
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.
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.
How you can know if your alternator is charging properly?
Check the voltage at the battery posts with the engine idling. It should read from 13.5 to 15.5 volts.
How do you know if your alternator is gone?
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
Can an automobile battery be recharged just by driving it a long distance?
Yes, if the alternator is functioning and you are not loading the charging circuit (using as much charge as the alternator is putting out so the battery receives nothing). Please note that "Idling" to charge the alternator normally does not work as the alternator is not turning fast enough to charge the battery, it only maintains the status quo for energy usage.
Why would your car volt amps drop while you stop at a light?
Engine is idling too slow or the alternator is weak. Or battery is getting tired.
Why does a Chevy S10 make a light winding noise when idling and the battery gauge drops when you let off the accelerator?
sounds like the alternator is going bad.
Does the alternator charge your battery when the car is idling?
Yes and no. Yes: The alternator will charge the battery any time the engine is running (even at idle) if the battery's voltage is below the threshold (usually around 12 volts) so that the voltage regulator triggers the alternator to generate power (around 14 volts) until the battery is charged up. No: If there is not enough consumption of power, the battery may be charged enough and the voltage regulator will not trigger power generation.
How can you know if your alternator is bad?
Check the voltage output at the battery posts with a multimeter set to DC voltage in the 20 volt range engine idling. You should get from 13.5 to 16 volts. Any more or less and the alternator is bad.
