I have a 12K # Stealth winch on my 2018 Wrangler. Nylon rope. As soon as I connect the remote control wire, the winch starts to wind in. I have traced this to the remote itself. I borrowed a new remote from a friend, hooked it up via wire, and it works fine. So that points to the remote...
You were right. I replaced the high current fuse array as you suggested. Success! Thanks. Next time I'll remember to be more careful when changing the battery and handling the leads.
I suppose it could have been fried while replacing the battery, although that would be a bit or a coincidence. But I've been seeing threads where folks had all sorts of electrical issues after changing out a battery.
I have a 2018 Wrangler JL, 2.0 L engine. Recently the main battery died and I replaced it. I was also going to replace the aux battery but discovered it had already been removed (bought the Jeep used). Anyway, new battery in place, the vehicle started right up, but now I have a Power Steering...
