I'm updating the wiring to the lights on my 4020. I'm about to reinstall the lights but wanted to make sure I'm doing the right things to get a good ground path back to the tractor.
I'm going to wire brush the bolt on the back of the headlight. I've already used a sanding flapper wheel on the back of the big round washers. I've sanded the inside (front or dish) side of the small, oblong washer as well as the back side where the nut will make contact.
How much do I need to sand the recess in the fender where the headlight sits? Should I sand only the front, or also sand the back where the smaller washer will sit?
I also know to make sure the cast fender base and axle are clean and to give all the contact points just a touch of dielectric grease.
Any ideas?
