Can someone with a 1990 RC take a pic of the back of there alt. for me so I can see how it is wired, I had a small fire engine fire and I need to see how it was wired, have a new alt. and wires just want to make sure I hook it up right, Thanks Larry
well,the big post is battery positive, blue wire is ignition positive (small terminal towards passenger side) and the green wire is computer control- small terminal towards drivers side. there may be a second large wire-its for ground.bigger stud on top of alt.case. i did take photos of the rear of the alt,still in my cam at work.
they will soon be found in a how- to for regulator retrofit for computerized trucks.
