Thank you, this helps. I already purchased a one wire alt. so I'll be using this one.
So 8 gauge wire should be fine?
On another tone, I can't seem to find a backup switch on my tranny. I found a round thing with a single pin sticking out. Is this it?
I would rather use the one that came with my 50 but I think I got rid of it. The tranny is a late 60's chevy 3spd.
