Stop in for a cup of coffee

We found the short, it's the entire fuse box, literally it has melted and there's at least 10 fuse terminals all melted into one. As soon as you hook up the battery, the blower motor kicks on and the taillights flash, smoke starts pouring the moment the key is turned, gonna rip the entire harness out but I just wanna see if it'll run enough to pull itself out of the yard. It's too wet and has been all summer to get my trailer and truck in there to winch it up
well, not going to happen with it wired up normally... I've never done it but there has got to be a way to disconnect the main power and run some auxiliary switches to power just the engine
