Chef Clutch, thanks for the hospitality and some killer pulled pork!
Here's the technical deets:
-passenger headlight dim, driver okay: Western plow harness from previous vehicle installed. Crusty looking spade terminals on relays, 4.2v on low beam, high beam inop. FIX: clean bulkhead connector, discover bent pin for unrelated wiper circuit. Replace hardwired relays with conventional 5 pins on sockets, ground headlights directly to core support, eliminate spade connections into factory plugs.
-inop fuel gauge- FIX: determine proper wire color for sending unit for 87 sending unit and 80 fuel gauge (it's pink, btw). Confirm gauge is good, rewire from tan (pump power) to pink (sender), locate pink wire on firewall side of bulkhead connector ("this pink wire is hot all the time, and I have no idea where it goes", hey, it's got the same 8.1v as the back of the gauge, what happens when I ground it?, the gauge moves, ok, let's hook it up!)
-inop oil pressure gauge: locate brown wire in engine compartment, determine open circuit in 3-4 feet of wire. EASY FIX: laser bypass (new wire from sender to cluster plug.
-crazy gauge and turn indicator operation: folded over ribbon pin on PCB. FIX: carefully straighten and install plug.
-inop high beam indicator- FIX: install bulb socket
-intermittant accessory power with no power on key back to accessory- FIX: buy new ignition switch, drop column, determine switch is incorrect, return switch, get interrogated by manager, point out flaw, get refunded, go back across town opposite direction, get new switch, and install correct switch.
It was a great weekend that truly defines what GBF is all about- meeting great people, sharing a common interest and helping each other out.
