grounds

after i raised my 27,s body 2" and installed spacers i noticed my throttle cable was welding itself to the firewall
i mentioned it to my mechanical geius guru and 1st thing out of his mouth was.
ground the engine to the frame and do the same to the body.
he gave me 2 of those copper braided straps.
ran one from the block to the frame a 12 inch strap.
and one from the body to the frame a 6 inch strap.
i cant believe i forgot the fact that almost every electrical gremlin i have ever chased was a ground problem.
i just figured i'd post this in case somebody gets brain damaged and forgets the importance of a good ground.

Good reminder!

My sedan is a fiberglass car, so I had to run dedicated grounds for everything. If I re-wire a steel car, I think I might run the grounds just like I would for a fiberglass car. It would take a lot of the guess work out of "is this circuit properly grounded". My only electrical gremlin was an LED turn/park signal that had an internal short - new light, no more problem.

starter

Of course the main battery ground cable is connected to the engine block because the starter is the only load that requires a very high amp draw.
