wouldnt it make more sense to ground there at the frame? small self tapping SS screw.
I`m asking cause I'm trying to learn.
It makes "sense" if it works. But if it does not work, and you have read my explanation on the path that the ground has to take, you will understand that a direct wire will fix it or prove it's not a ground problem. There are other methods to troubleshoot (per my link) and member suggestions. The direct wire is a reasonable fix nevertheless.
We all agree that the best idea is to use a backup jumper from screw to frame. The 60-66 trucks have a special tab on the sender to wire directly to cab wall. Chevy started to recognize the problem.
