Can someone please educate me on how the voltage stabilizer on my TSC is grounded? Below is a picture of the back of my original dash. The ground wire is screwed into the dash. How does this ground the stabilizer? Would it be better to run a new ground to the chassis?
Thanks,
Sherman

The grounds from the dashboard should be all joined up and earthed to the chassis where the two metal brackets hold the dashboard at the bottom. They are bolted to the chassis by about 1 1/2" x 3/8 UNF bolts just behind where the heater pipes emerge from the chassis.
The brackets are about where the two window switches are located.

That sounds logical, but my voltage stabilizer only had the ground wire attached as in the picture. I think I will run a dedicated ground to the chassis bolts located as you described.
Thanks!

There is no ground wire terminal on the reg itself. Just ground the body of the reg. Some instrument voltage regs don't even have a ground.

I had to run a wire linking up the door switch earths, and all the dashboard earths to get things to work properly.
Likewise, all the front lights earth to a 1/4 UNF bolt which holds the metal closer plate to the body. That plate then earths to the chassis where that steel closure plate is bolted to the cross front T of the chassis.
So remove that closure plate, and the lights etc won't work.
