I have a gauge that tells me the volts when the engine is running and the battery voltage when resting.
I wanted to know if it is normal for the alternator to put out 12.2 - 13.3 at idle at a light from time to time and then go 12.5 - 13.5 with only the a/c running in the daytime? (non-electric fan)
Also the battery at rest (engine not running) will go from 12.5 - 12.2 with nothing on ?
The car starts fine and would not suspect a thing if it was not for the gauge.
Do i have a bad battery or am i concerned over nothing?
Anything you can tell me about batteries and alternators would be helpful!!
