High volts

Plum Crazy, my newer cars read 14.5 V w/ engine running and 12.6 V with engine off. That is at the cigarette lighter with a plug-in voltmeter ($15 Equuis via Amazon). I recall about the same in my old Mopars. Sounds good to me. Your ammeter shouldn't stay at 3/4 scale continuously. If it does, it means a lot of current is flowing into the battery but the voltage isn't increasing. If so, stop at Autozone or such and they will load test your battery for free in the parking lot. You could have a bad cell or low water. The current will be converting the water into H2 & O2, which will disappear.

Had that done already, checked good. The only thing they found was a slightly low starter amp draw 11.97 v ? Haven't been driving it for fear of burning something up.
