Ground to Powder Coat Frame

[Nevinsj]

I powder coated my frame, do I need to grind away the paint at the ground wire connections for a good ground?

Yeah it needs to bare metal to bare metal. I use dielectric grease on exposed connections, you can usually get it at Lowes, Home depot as Ox Guard made by GB in a small red tube. Any electrical supply house will have it as well.

I got some at the local autozone

I powder coated my frame as well. I'm getting close to hooking up the battery again but just assumed that the threads of the bolt making contact would be fine. I was thinking that I'd put a washer against the painted frame and then sandwich the the connection between the washer and the bolt head. Since the bolt then runs through the frame ( bare metal to bare metal) I'd be good. Why is grinding off the paint necessary ?

A bad or intermittent ground can cause so much grief I just don't play with them. I get as much metal to metal contact as possible. That way I can feel confident with that connection. Threads do contact but wouldn't have near the contact surface area as a flat washer, use the grease and you won't have a corrosion problem and a solid ground.
