Re: 1972 does not turn over when hot
I wired my truck with two batteries and two solenoids and an isolater. When I turn the key it gets starting power from both batteries. When its running it is only running off one battery but charging both. I run my trailer brakes and other accessories off the second battery. Camper etc. A tough concept to wrap your head around but I had hard starting problems even with a new switch. Now if I want to bump the engine I just put my starter switch on the solenoid right there by the battery. Much easier than fighting my way through the header with a small alligator clamp and hoping I find the right lead when I cannot see a thing. OH yeah and that mutha will start a tractor and my truck at the same time now! (stock starter too) around 9.5-10.0 compression I guess.
It isn't "pretty" but my wife is!
