I have an older Crafstsman Lawn Tractor that I loaned to someone and it came back unable to turn over. I checked the starter and it was trashed so replaced it and motor still will not turn over. Installed a new solenoid, ignition switch and operator presence switch under the seat and still no success. I had replaced the switch at the clutch pedal last year so don't think that's the problem. The 30amp fuse at the solenoid is good as well as the battery. Any clues on which direction I should go from here? Is there soemthing I'm missing? Thanks Ahead.
