I recently started resurrecting a '93 Ford F350 (5.8 liter) that has been sitting in my driveway for more than a year having been started only once or twice. Of course, the battery was dead and wouldn't take a charge. With a new battery in place I started the truck and headed for the inspection station. Enroute I hear a significant whirring/whinning noise. I'm thinking it's a dried out pulley or alternator bearing? About five miles down the road the truck dies, and will not restart. I smell an electrical smell. While my son is on the way with the jumper cables, and I'm thinking my alternator is gone, I discover that the starter motor is flaming hot. The jumper cables don't help, and I'm off to the parts store for a new starter. Once installed the truck starts right up and I head home. Same noise. Almost home the truck dies again. Won't jump. Starter flaming hot, and electrical connection points melted. Now I realize that it's the started that's making the noise because it's continuing to run. Duh? New starter relay switch and started installed - same thing! Starter keep running! Can anybody point me in the right direction?
