Master cutoff switch

[Gmirza]

Thanks guys,
I used a Joe’s 4 pole 250 amp from summit. I ran the batteries through one side and I put a painless cv solenoid in the alt-batt. Line and ran the activation power wire through the other poles. It works perfect, shuts the car down and kills all the live power in the car.
I tried running the alt-batt wire through the switch but I was getting a big voltage drop at the batteries. Just to much wire length, the solenoid solved that problem.
