Cut off switch

[Tom Goldman]

Heres a shot of the disconnect switch I installed on Ron Muffetts gen 3 Camaro Stocker .
I modified a Lokar cable operated switch to work under the hood rather than in the rear as the car utilizes just the one battery . the control handle is inside next to the shifter.
Solenoid operated relays are a good idea for killing a alternator but involve maintaining power to the control switch. I would avoid using them in favor of a mechanical switch.

All good ideas but I was thinking of how track personnel would turn it off in an emergency, in back it’s easy but not wanting to run big cables to front. I’ve been thing about the solenoid thing too but didn’t want it egauged while in use.

Not a class car but I am using a high amp relay and E-stop buttons on my steering wheel and on the back of my car.









Rear button

Relay

Just use a on-off switch with a negative or positive wire hooked to the solenoid. It can be a 14 gauge wire, The wire connects to the small studs on the solenoid. Hope this helps.

I wouldn't cut the negative side. If you have a wreck and the wire gets cut and goes to ground the relay won't shut off.

Absolutely !. Rule book also specifies interrupting the positive side only.
