I bought a 77 f150 351m. It was wrecked very light in the Rt front. When I bought it, it would not start. WE put a used starter solenoid on it and drove it home. I replaced fender and hood in the back yard and it would not stard. I taped the starter solenoid it started and ran for 15 min or so. I started it about 5 more times no problem. Started it up and noticed the starter solenoid smokin that was the end of that solenoid. I put another used solenoid on it started it up to bleed brakes, drove it over the hill and started back up the hill and the truck died. I thought it was out of gas. Today I put gas in it cranked it up and before I could get out of the truck it melted the + side of the solenoid. All my wires are ok no bare places or anything like that. Any ideas would be a great help. Is it posable the starter could be bad?
