put the new alternator in ..

and it seems to be good..


but my voltage at idle with the headlights on is roughly 13.7...
if i shut my headlights off...voltage seems to drop...what the hell is up with this.. shouldnt my voltage go up..with less accesories runnin?



any ideas at all?

what is the voltage with no accessories on?

I think the voltage is supposed to stay the same as long as you are within the alternator's output range.
