I have a Crapsman mower that was running. I had turned it off for a moment got back on it and now I just get a single click that appears to come from the starter area. It has a safety switch on the seat. If I have the key in the on position and press down on the seat I get the same click. The lights also are working. I have tried the following: - Starter and solenoid have tested good at a local shop - Battery has tested good at a shop - Tried jumping it from a car Could this be the ignition switch or possibly the safety switch on the seat? Is there an easy way to check the safety switches?
