Fabricated ground block
Another item that needs to go on the firewall in the ground block. I cut a piece of .063 sheet to size to fit 3 of the ground tab clusters I bought from SteinAir. Each has 10 tabs on it for a total of 30 tabs. That should be enough. I countersunk the back of the sheet and then rivets the tab clusters to the sheet. Looks simple. I just need to figure out the bolt size I need and then attach it to the firewall above the battery. Forgot to mention that I tested the resistance between various parts of the ground block, and it was all below the level that my multimeter can measure.
