I have recently purchased a 3000 lb winch for my trx 300 4x4. Power for this winch runs directly to the battery so I would like to put a hidden saftey shut off switch to keep the kids from tearing things up. My question is will I lose power or damage anything if I use a 50 amp rated switch on the ground wire to interupt the circuit. The winch pulls 100 amps and I was told the switch might get a little hot but it should be fine. any advice?

 

Ya it could melt , had it happen to me on my boat ,I had a 24 volt set up for the trolling motor an breakers melted about the 3rd time out .Scared the heck out of me an my wife !!!!!! If you have to run heavier wire an you kin find the breakers that you need to do it right .....

 

I would just wire it in to your key switch like should haver been done in the first place this way if the key is out of the machine no one can mess with it good luck

 

second that ,best way to go !!!!

 

I assume it has a control contactor?
