I have a 1983 F150. When I tried to start the truck, smoke was seen from the solenoid, positive side that hooks to a fusable link and the battrey. I went and picked up a new one, and the same thing. Is it the fusable link that is burning, if so, where do I get a replacement, or is it a bigger issue.

The solenoid was really hot when I disconnected the cables. thanks in advance.
