'95 Grand AM 4 cylinder. The dash has both a volt meter and a battery indicator light.
When driving on the freeway (about 3000 RPM) with lights on, fan on high and the rear window defroster on the volt meter reads about 13.7 which is normal. The problem is whenever I use the turn signal or power windows, the battery indicator light will flicker. The volt meter does not drop below
13.5 volts. I would expect that an amperage issue the voltage would drop quite a bit.The weird part is when the engine is at idle I can stall the power window and the voltage will drop to 10 volts but the battery light will not turn on.
The alternator is fairly new and was on the car when I bought it
Any ideas what this means? Is the alternator going bad?
