I have a 1985 that has sit for some time it started good when I got it but needed some other work on the truck so it sat some time until I got back to it. I remembered when I started it the son said something about some smoke well I figured it out today. They installed a glow plug bypass and I noticed the black wire was melted pretty good. I moved these wires around a long time ago replacing the main battery cables and such so I am not sure what those were attached to maybe they were incorrect at that time. Looking at the relay the purple wire should be on the S terminal of the relay this goes to the manual switch, and the burnt black wires goes to the I terminal? What I can tell this is a ground, odd thing is I found some pictures on controller bypasses and there was no black wire. If its a ground why doesn’t it just go to the frame, and there is a ground that attaches to the base of the glow plug relay. Does that black wire need to be there?
