Stop in for a cup of coffee

Waiting for guy to pick up his engine core. I need it gone,so i can put fargo away. im picking away at it,pulled out ign switch and tested it. Was dirty but soaked it with contact cleaner and its consistent now. Wiring is in great shape... think i have some idea why it was parked.
Battery ground was attatched to inner fender,undersized and half melted as well. Getting it sorted so maybe it will move itself around.
