good afternoon my name is ***** ***** I will assist
the pcm, was it new or used. did you have it flashed to your truck??
what brand alternator???
I attached a wire diagram for you to view
can you check the voltage on both little wires that go to the pcm while running???
1 and 2
I will be here
ok, so the black wire has what voltage???
no, that means it is grounded. but you should have voltage at the other wire.
it concerns me that the pcm is the issue. I have no faith in re man units. the fact that it is charging too much tells me the alt is working but the regulator is the failure. that is part of the pcm.
they both could have had the same issue. remember, the replacement is not new, it is re furbed
ok sounds good
according to our checks, you had all the needed voltages. that would eliminate the pdc and the fcm.
it is possible. do the wigle test while running and see if the charge rate goes up
