Default Re: How to Properly Ground a Race Car

Ground to multiple points just in case one of them gets corroded, loose or whatever.

My 68 Mustang (my avatar) is street legal so it's full of extra wiring. My one wire alternator is grounded directly back to the battery in the trunk with 10 gauge wire. The battery negatives are grounded to tabs welded to the rear angle bars for the cage, one on each side.

Over the Winter I'm going to weld tabs to the stock frame in the engine compartment while it's empty and do away with any firewall or fender well ground wires.

I have a Painless Performance street strip wiring kit that includes a fuse block for street functions and a switch panel for race functions. I added a Bussman 12 circuit fuse box for all the extra gauges and stuff I have added. This made a rats nest of wiring under my dash so I just now redid it into a consolidated panel on pegboard under an aluminum cover where it's easy to get at. It's grounded to a tab welded to the 6X6 plate that the front of my cage anchors to.

It's all buttoned up right now, but I can take the covers off and post photos tomorrow if you want to see how I tried to tame this stuff.
