Holy Flameout Batman! Very sorry to see this. I had something like this happen to me at the Mopar Nats a few years ago. I had my car go totally black (no power, just dead) on Brice road. I jumped out of the car to check it out as going dead is usually a bad thing. I was looking under the car at the battery cables going to the trunk when somebody said you've got a fire under the hood. I hurried to remove the Dzus fasteners and remove the hood and almost had a guy break my hood by trying to lift it off before all of the fasteners were removed. I saw that it was a relatively small fire so I went to get a bottle of water I had in the car when Smokey The Bear with his new fire extinguisher blasted my engine compartment with white dust......and then the rain started LOL. Anyway it turns out that the Lokar branded steel cable I had rubbed against the main power wire (on the wrong side of the fuseable link) and set the harness on fire. Just like you I had to replace it. I feel your pain man. Good luck.
