question about voltage output?
 

it has done this since day one and I don't know why. but if I'm in drive and come to a stop, or close to a stop, my voltage will drop to 12.3(rpm's are about 500) and then slowly rise back up. but if I put it in neutral before I get to a stop, my voltage stays the same, at about 13.6-13.8.

does anyone else with a volt gauge that's auto notice this? or is it just my car? lol

?
