corrosion... may be a leaky windshield gasket... so putting a new harness will not really help.
As usual disconnect battery before doing any electrical work... because your year Model 85, the ammeter wires are live even with the ignition key removed, this was the last year for the ammeter... which is always ready to do a FSJ BBQ...
Fuse box looking crudy, disconnect battery ground cable and remove and replace fuses... at least the 85 fuses are the plastic ones, not the glass cylinders that are a pita.
Apologies in advance for rambling response!
I had figured it was sunroof related based on how much it has clearly leaked. Bad enough I had to sand and put POR15 on the inside roof (maybe overkill
). The cowl has very little debris and I do plan to replace windshield gasket. I’m thinking I should be less assumptive with the electrical. All power locks, seats, doors, tailgate, interior lights work. Really it’s just dash lights, radio and clock. Gauges don’t work, but I have a 79 instrument panel in the mail that has voltmeter conversion already done. I’m gonna also do the 7805 transistor voltage regulator thing you guys have posted. I already fried a CVR in mine because it was the 73-84 gauge. I just figured it would work. False!
The fuse box though....acc lps, ign lps, clock/haz, wiper, fuses are not showing power, yet certain related things work and others don’t. I.e. window defogger works, but not instrument feed. I’ve replaced all fuses and worked on the corrosion at the connectors. I’ve got deoxit in the mail and will work on it again. All this to ask, Michel....does your 85 have a 3 or 15 fuse for ign lps? I have seen diagrams that show different things. Mine has a 15 in there.
I guess one more question, should I not put the 79 panel in until the cvr bypass is done? I’m puzzled if the temp gauge in the 79 panel will be safe in my 85, since I fried the same kind of temp gauge in an 85 panel. Thanks to all you guys for answering. Such an awesome community.
