I have a few months old BT-80 on an F-Zero. From the get-go the starter just goes click (at the solenoid). This motor is electric start with additional pull start. I know a bit about electronics-electricity so I made sure the grounded green wire to the engine is good -- on bare metal. So I have replaced the solenoid, the starter and the throttle/ignition switch and it still goes click. I don't know if the CDI has anything to do with the starter circuit. All other wires are correctly connected. Battery is a fresh LiPo. Any help much appreciated.
