Well. When the engine is running, the alternator is charging the battery. So I'm thinking the gauge is going up and down with your idle, not the other way around.
Heh, UNLESS ... in the completely highly ridiculously unlikely event that your batt. gauge is shorted with your tach. LOL, don't see that happening though.
