Beltfed,
I already have a grounding strap from the frame to the bellhousing. I will add a grounding strap from the body to the transmission. If it ever stops raining here in Ohio, I will clean the existing ground strap connections, and then clean the connections of any wiring from the battery to the tail lights. Is there something I can use to keep these connections from corroding, or at least slow it down - like a paste or a spray?
