So I have been hearing a lot of chatter recently about winch power safety and if you should be using a fuse/relay/power cut off in a winch system, and I think this subject may have the most broad set of opinions & theories of any topic I have researched related to my rig 😀
Having a decent understanding of how electrical circuits work and the damage they can cause, I get why you want some protection (when wiring dual batteries in my old boat I dropped wrench between the terminals and boy did it jump off of them with a flash of lightning), but seems like many winch manufacturers recommend against fuses and relays to prevent restricting power flow. So thinking about the risks and probabilities, my feeling is that having a device directly connected to a power source 99.9% of the time to use it .1% of the time is probably the biggest risk, especially when the rig it is parked a large amount of the time. Yes something can ground out when you are using it, but you can take actions, if that happens sitting in the garage it is a bigger deal.
So I am considering a power shut off, disconnecting the winch from power when not in use, probably something mechanical that I turn on when airing down. Is anyone else doing fuse/breakers/power shut off's or have an opinion?
