Isn’t there a grease you can put on electrical connections to prevent that?

Crusty voltage regulator pins are extremely common and I usually cut off the terminal and crimp on a new one if it is bad enough.

Dielectric grease makes connectors easier to pull apart and I put a touch of it under body ground connections.

I’m dealing with a failure to charge on my XR7. Will be pulling my alt harness and testing it this evening. Eager to see how your repairs go.

Dang. My problem is still there. Fresh alternator, fresh alt. harness, cleaned VR plug pins, cleaned block ground. What the heck? Next thing is to try swapping out the VR. I even scuffed the paint where the VR mounts to make sure it was grounded to the car, if that even matters.

The VR I have is a solid state one I got from the auto parts store. Initially, I was going to swap out the cover panel to a more original looking "Autolite" labeled one, so I drilled out the rivets for the cover. It still didn't want to separate, so it looks like I drilled out a third rivet towards the top / middle of the unit. I'm thinking that was some kind of ground lug and I shouldn't have drilled it...

So. As I'm writing this, I just went and swapped out the VR with one of these. Just ran it for a minute but so far it's looking like that may have solved it... will have to do a longer drive to know for sure.

I've had issues with new voltage regulators. If you've already addressed that my apologize for not reading the whole thread in full detail. Since everything else seems to have been addressed you might check or recheck with another known good regulator.

Yep. Having driven the car a couple times now with a new voltage regulator, that seems to have solved the problem. It didn’t hurt to address the other things though.

It wouldn't hurt to put a little dialectric grease on those connections but good job cleaning those connectors.
