What are the signs that an alternator is going bad?

One way to tell if your alternator is going bad is to start it up, preferably at night, and turn on the lights. Then turn on the the heater fan. If your lights get dimmer when you turn on the fan the alternator could be going bad. A common problem with an alternator that is insufficiently charging is having to jump start your car even after you have run it beforehand. The best way to test it is with a volt meter. You should read 13 to 14 volts across the battery while the engine is running, if you read less your alternator is insufficiently charging. Another way to test it is to take it to a parts store for a free test.

What wrong when the instrument panel lights dim when AC is turn on?

When you turn on the A/C the engine RPMs drop slightly. If this causes the dash light to dim slightly then I would suspect your alternator is weak or the drive belt is slipping. Check the belt and adjust or replace as necessary. Also check the output of the alternator with the engine running at idle. You should get a reading of 13.5 to 15.5 volts on a digital volt meter.
