ALT wiring

blue83ranger · Jun 17, 2013

I'm just finishing up durasparking my other '83 2.8 ranger and noticed when I took the ALT wiring out of the harness to put back on the truck that one of the wires doesn't hook up to anything. The plug is on the drivers side, and on the cab side is suppose to have 8 wires in it and looking on my 1st '83 ranger it's suppose to have a white wire and this ranger has nothing. So, does anyone know where that wire goes or what it does?

There is an '83-'85 charging system diagram here:

Those years had a separate voltage regulator(external), yours may have been updated to an internal voltage regulator at some point.

I haven't checked any other wiring but there's still an external regulator on it and when I first got the truck there was no alternator on it at all. I put one on we had laying around from a 390.
