I have a Sears 917.254850 that keeps blowing fuses. Here is what I have done so far. Removed the plug at the alternator and still blew the fuse. Removed the wiring harness and inspected all wires. Found none melted or fused together. Replaced the terminal at the starter solenoid. Replaced the solenoid. Replaced the ignition switch. What am I overlooking? Could one of the safety switches be cousing this?
