Hi Davideo,
Congrats on resurrecting you Bullet and welcome back to the REal world
Sad to hear the gremlin named electrickery jumped you but I'm sure you can handle it.
Sounds like there was a dead short to ground.
By my estimation you could repair what fryed or rewire to suit.
Me, I would repair as needed and maybe split some windshield washer fluid tubing and slip it over wires that look like they might rub and keep rocking.
In case you decide to rewire below are some schematics from our forum brothers.
Let us know how you make out,,,,,,,and welcome back
