Had a few minutes after work, went and looked at a few things tonight. Just looked, didn't troubleshoot

The underside of the relay holder looks shiny and new.



I also pulled the plug to the computer. All the pins look like they have a 'waxy' coating on them, some more than others. Normal? (crappy pic, I know).





I did find something odd, if not confusing. Not one of the ground wires going to the drivers fender was tight. The screws were tight, but in a cross threaded kinda way, leaving the wire loose. 2 of the terminals had no witness marks from the screw. I find it hard to believe this thing has been running around for 28 yrs with half its grounds not connected,

I'm wondering if the computer did finally die partly due to the lack of proper grounding?
