My 1991 f250 7.3 idi and the issue is that my truck won’t charge unless I jump power to the field wire. After that it charges fine. I do have a broken ground cable and I have replaced my entire charging system.
This! I fought with regulators till I got a good one. The more expensive ones seemed to be junk. Im running the cheap one from orileys and I carry a spare.I went through 3 regulators from Napa just get one good one. Finally switched to 3G and never looked back.
if that light doesn't work, the battery won't charge.......
Don't do this, though.3G wiring.
