Thanks Ken. New truck was going to happen one way or another. We had hoped to keep the Colorado and get the issue resolved but after the ordeal of not starting and the voodoo that happened yesterday we just said enough. I left no letter, but I suspect they will be long shortly on their own. During the drive to the dealer yesterday every time I'd hit a grade, the battery light would come on even though the engine RPMs were constant. I'd bet it is either that ground at the PCM or the PCM itself. That PCM gets very hot. I never did put my IR thermometer on it, but it was hotter than I'd think a computer should be.Congrats on the new truck, Mike.
Did you hide a note in the glovebox pointing to this thread for the new owner?
I've been following this thread and I'm glad to see you keep posting updates. Your findings could really help someone else down the road. :thumbup2:On the drive in this morning I did not experience any issues.
Not sure if the removal and reinstall of the computer and alternator wiring harnesses did something or if it is just the lower temperature this morning.
Supposed to be mid 90's and high humidity on drive home this afternoon. That is the scenario that usually makes it the worst.
Thanks for input.Ken,
I still think that the alternator is the cause of your electrical issues. It has a p.c. Board internal that controls your voltage. I would apply some heat when on the bench testing it. I think you have been so involved chasing electrical gremlins, it’s easy to over look what you have been chasing.
