Hi Paul, Its Dan. What is your machine serial number? Test all your fuses for power on both sides with the key on by probing the top tabs of the fuse. Should have power on both sides for a good fuse. any fuses with power on only one side is faulty. If ok you could have a faulty relay, starter, ignition switch, or safety switch problem. Test for power at the starter solenoid small S terminal wire with someone turning the key into the start position. If there is power there , battery and cable connections are good, it means the starter is bad. Let me know
