decided to finially dig in and clean up some ground connections last night. Started with the stud that connects to the (-) from the battery. There seems to be a "plastic" washer behind the nut/washer/wire. It also seems to be fixed. Is this original?
I would have figured the wire would have grounded directly to the body not just to the stud connected to the body. any thoughts...pictures...etc.... I'll take a pic of mine tonight |

Not original AFAIK.
It is sometimes a good idea to add a cable from the stud on the engine wall to the fan shroud. This would make a more direct path than through the body, to the transmission ground strap, through the transmission, and through the engine case. The alternator is grounded through the fan shroud, and the starter through the transmission case. Even solid appearing bodies are not the best conductors. |

In front of the distributor there is an untapped hole suitable for an 8mm bolt. No idea why it is there, but I found it most useful. Get an automotive ground cable (I think about 2 or 4 AWG) of suitable length.

I added two grounds- battery stud to starter bolt (AWG 2, first pic), and alternator mount bolt to the ground stud that is under the relay board (AWG 8, second pic).
Whatever you do, I recommend sandwiching each lug between two internal tooth star washers on the stud or bolt. They cut through corrosion, bite into the steel, and form a realtively gas-tight seal. And they're very very cheap!   |

Am I lost? I was looking for the originality and history page ............... Done properly, the existing ground connections are not only sufficient, but correct and original. Anything else is, well, not. The Cap'n
