Battery solenoid as kill switch

Postby lowblazin94 » Wed Nov 16, 2016 7:50 pm

What's a good brand these days? I have everything on a switch panel but will be using the column key as a "kill switch" to a solenoid. I am doing this for those "oh crap" moments since that's peoples initial reaction is to turn the key off.

Can I use a Ford solenoid in line with the main accesories power cable? One cable is going to the starter and the other cable goes to the power distribution block. The cable to the power distribution block is where I will put the solenoid and wired to the key in the steering column.

Also everything is electric, water pump, fuel pump, radiator fans, trans cooler fan. Needs to be able to handle the current through it

I would think you would need a latching relay... The ford solenoid is not meet for continuous duty. It will get to hot and will shut down when you need it most.

Nice idea but I would not want all of my power on a relay. Sometime just a hard bump can trip them off. I would put the key input to a relay that just kill power to you ignition. That is just my thoughts...

There are some rated for continuous power. That's why there's the difference in the relay and solenoid/kill switch terminology. Gets confusing but i'd like for the driver to be able to kill all accessories

I can kill all power on my truck from the cab. I have a cable that run back to the kill switch. Good luck with your project.
