Yeah, I meant did he reset the CPU before starting the truck with the new alternator in it. PLUS, I am wondering if he is getting no charge out of it as in what is he measuring the amount of charge with...and where? The way to do it is with a VOM on the battery for a pretty accurate reading, but at the gauge.
plain and simple , pull the battery cable off, truck quits, checked back of alternator for magnetic field.. none, changed ecu works great charging and truck runs pull batt cable off and it does not quit, put old ecu back in truck with battery cables disconnected , and does not work.. = bad ecu
