Here is my 64 Valiant. You'll notice I have two large ground cables. One to the block from the batree and one from the block to the fender well. I'm sorta particular about having grounds.
oh thank you very much. That make sense, I have to look for that clamp between the in and out manifold. Gives a more sensible routing. I like good grounds too. And I have low voltage many places on the car, so that might come from missing ground between engine and body. The way you put it, it sounds like the ground is something you put on. Does this mean the car did not have a ground wire between the engine and body from the factory ? If I didn't know any better I would have guessed that they had a braid somewhere.
