Yea, I rewired the instrument cluster with the yellow and red on the same post. Will wrap it up and call that good for now.
Recap that I cannot make sense of:
-Pulled instrument cluster to replace bulbs with LEDs
-On reinstall, many things didn't work and/or were haunted and only working sporadically or in weird situations.
-Battery charge dropping rapidly during testing, eventually nothing works
-After replacing all that is listed below, hooked up to battery today and got a big spark. took out and reinstalled fuses, no spark, was able to hook up battery. No drop, so that's good, but the wipers are randomly engaging even though the switch is off.
-Some of the wires that were showing high resistance yesterday are testing fine today???
What I've done:
replaced the alternator
replaced fusible link at starter solenoid
replaced starter to NSS connection
replaced heater switch and connector
replaced ignition switch and connector
replaced floor dimmer and connector
replaced ignition coil connector
replaced headlamp switch
replaced fuses (some 20s had 25s in them)
tested for resistance everywhere (found high resistance at gry/blk @ floor switch and @ lt brn coming off heater resistor)
had battery tested and charged
Found this ground up under the dash where the wipers are top of the stack. I'm getting resistance readings that are all over the place? One check it reads high, the next it's fine? Trying to find what the other grounds go to, but they go into a BIG wrapped bundle.
