Here are a couple of photos of the regulator; it says “made in USA” on it, but I can find no company name. Unlike the original that I replaced, this one has no adjustment screws. All the contactors look clean; the battery contactor (cutout relay maybe?), has a slight bend in it so the contactors do not meet up square. But the contactors are convex anyway, so I don’t think that would matter much. I’ll clean them up just to make sure that is not the issue, and run the truck with the cover off to try to see which one is not working correct.
