voltage slowly drops after driving
Figured id go on a post spree lol. So when i start up i get 13.8VDC. after it gets warm and 20 minutes later its slowly drops to 13-13.2 at cruise.
Heres my thoughts: I just ordered an o2 housing heat shield as i dont have one now. Im guessing, i know a thing or 2 about electronics, that as the o2 housing heats the alternator and wires in and out of it, resistance is increasing causing more of a voltage drop. It DOES look kind of cooked too.
Do yall think the heat shield will help? I mean it cant hurt. If not perhaps i should run new alternator wires. Ive measured at battery(in trunk), junction up front, and off the alternator, they dont vary more than a tenth of a volt.
Im a clinical engineer and have seen how heat can destroy components.
