1989 Chevy Truck V8 Four Wheel Drive Automatic
I recently posted a question about my charging system problem and have yet to hear any response. The alt is new, grounds and fuses checked out good. Voltage regulator isn't engaging when truck is running. The old alt tested 14.5v but had bearing issues, while on the truck the old one only showed 12v. It was tested by advanced auto after changing alt didn't fix the problem. There is no power coming off harness for the alt(brown wire). Gauge in the dash reads the same as multimeter when truck is running(12.16v), with the truck off battery reads 12.5v and I don't have starting problems just charging. What am I overlooking?I need my truck up and running to get to my doctors appt. Everyone I talk to can't figure it out. Hope to hear from someone soon.
have the same problem?
