I replaced the relay and switch for the winch on my ’87 "new to me" 350 Fourtrac.

So also added a inline fuse with a 20 amp fuse. The winch with no load operates just fine. A slight load blows the fuse. The wire size is 8ga to and from the battery and relay. Researching I am thinking even the wire size could even be greater maybe even 4ga. I dont know.

I dont imagine pulling more than a few hundred pounds when I use it but who knows.

What should I be using for wire size and fuse amperage?

When it comes to determining this Im lost. Sure could use some advice. Im thinking to begin with using a Cole Hearsee 80amp circuit breaker. with my current wire size.

Thanks Tom
