How long is the ground strap on an RB 1970 b body and where does it attach to the engine and firewall? How is it made? Braided copper or?

I've only seen them listed for '69 back. I bought one at local AP store, a Dorman brand, braided and tinned approximately 10" long. Bolted to rear of driver side head with 3/8-16 bolt and to Starte Relay mounting bolt.

70'S use an auxiliary wire that is part of the neg battery cable to the radiator bulkhead near the batt.
There is a welded, threaded boss there to attach the smaller ground wire.

The Headlight Harness Grounds to this boss also. I added the strap for overkill. Also ran ground wires from Taillights to body.

I agree, ground every damn thing twice!!

Joe

as said , there wasn't one , cheaper to add a small wire to the negative cable and run it to the core support using existing ground point.

But adding one won't hurt.

Thanks guys. I am relying on my rusty 25 year old memory on a lot of this stuff.

Did the original battery ground cable have a second line that came from the engine end or the battery end?

Battery end...I think I got mine from NAPA.

Joe

Thank you!

The cable had a ground wire at the battery for your head lite ground, it screws into the front of where your battery sets. My 70 has an original ground strap about 8-10 inches long and about 3/4 inch wide on the back of the passenger head and bolts to the fire wall. Good Luck with it

Hmm, I never saw one on my Charger???
