Battery ground wire and hot wire section

Hi guys,

Thank you for your replies.
The kit I bought came with a 2 gage red wire and a 3 gage black wire both 14 feet long. I had difficulties trying to crank up the engine and wires were hot so I guess I have to replace them. I will go for a 2 times bigger red wire but I wonder if I have to pay to replace the 3 gage black wire too.

I'm not sure I'm clear, or maybe I didn't understand well but I don't use the frame to carry the ground to the engine : I routed a wire from the battery to the transmission bell housing bolt and then the frame is linked to the ground with a short wire routed from an engine mounting bolt to the frame.

I don't get your 2/3 ga? According to the kit link you posted, those cables SHOULD BOTH be 1 ga.........You sure that is the kit you bought? If so I'd be double checking and contacting Ron Francis!!

In deference to above, YOU CAN use the unibody as a ground, hundreds of us did so "back in the day" but modern electronics, etc, this method has fallen out of favor. The unibody in these cars, being all welded construction, makes a pretty good ground. I did this way back "in the day" in my 440-6 '70 Roadrunner. That was with a wound field (old style) starter, certainly not a "mini" starter
