tonedeaf Posted July 30, 2011 Report Share Posted July 30, 2011 At the same time, you realize its 100+ degrees here, not sure what it is where you're from, but I would imagine that might also effect it. Quote Link to comment Share on other sites More sharing options...

audioanonymous Posted July 30, 2011 Report Share Posted July 30, 2011 I dont know if you did this or not, this is only something to consider, but when you first checked it was your air conditioner NOT on in your car and it is now? Because that load usually lowers the voltage. Just something to think about if you have an added load on the vehicle now when it's running.

kickass audio Posted July 30, 2011 Report Share Posted July 30, 2011 I had this happen with my 04 envoy. The alt is regulated internally by itself so its not like the newer vehicles where the ecu controls my voltage output on the alt. The problem mine had is that the ground from my battery to the engine and frame was getting rusty. Everytime i cleaned it up, my voltage would come back up to 14.9v warm but when it got a little bit of rust, it would start to drop back down at 13v. I also noticed a random "dancing" affect of my volt meter in my dash when i first started my truck up. The voltage would go up to 14.4v but drop to 13, go up, back down, and then stay steady. As soon as i fixed the ground it worked fine. I would just double check your positive and ground wires in your engine to make sure they have no corrosion or rust on them and go from there. Mine was extremely sensitive to rust and would screw up my charging system a ton with it.
