Check all the battery cable connections. Pull up the access panel at the pedals,there is a 2-prong connector for the pedal-switch,make sure its' not damaged or corroded. Check the ground to the electrical-panel under the seat on the driver-side.My Wifes' G16 would run perfect,then not at all.The ground from that panel into the main harness was bad. I ran a new ground from the panel to ground,problem solved. Also check the solenoid with a test-lite. One small terminal gets power when you press the pedal, which then energizes the large terminal going to the starter/gen. If you are getting power to the small terminal, and not the large when activated, or not hearing the solenoid click, replace the solenoid.Hope this helps.
