Mouse nest in the tail lights:
New fuel filter and hoses:
Differential mount was torn and the diff was clunking every time you let off the accelerator:
I threw a new set of NGK plugs in.
The tach wasn't working. I found the plug for it hanging in behind the dash and got it reconnected. Tach works again!
One thing I haven't figured out yet is why none of the parking lights, marker lights, tail lights, or dash lights work. The headlights and high beams work fine though. All the fuses are good. So I'll be working on that next. I've got power incoming to the light switch Via the white/red wire. And the switch powers the red wire with the switch in the headlight position but neither the green/white (which seems to be common color on every parking light bulb) nor the green/blue wire coming off the switch have any voltage. Has anyone taken one of these headlight switches apart and cleaned the contacts?
