For a change of pace, I have just finished upgrading my electrical wiring for the battery, alternator and grounds. I had high RPM voltage drop with a couple alternators, different pulleys, and with 2 AWG positive wiring to the alternator. Coupled with that is my big stereo and sub upgrade project drawing more power. So the battery terminals were messy.
My Build Level
Hydraulic Crimper
I found several issues with the wiring:
1. Importance of good grounds. For a car never driven in the rain, no salt, etc., with 22,000 miles, the grounds were in poor shape.
Stock engine block to frame
Completely rusted underside of engine block nut.
Self tapping screw (!) used on other end to attach to frame
