I have a family member with a 2008 EZGO RXV golf cart that only has a solenoid click whenever the key is turned to either Neutral or Forward. It does not move at all or make a solenoid click when the throttle is pushed. The batteries are pretty new and all of the other electronics respond, reverse beeper, horn, lights, etc. "Fuel" guage shows fully charged. We do not recall the solenoid click when turning the key prior to the cart failing to run. Any idea what could create this symptom?
