I have a 48v 2009 EZGO RXV that wont run. New batteries and new solenoid. Solenoid reads 54 volts with key off but jumps to 0 when key is turned to F N or R. Also solenoid clicks when key is turned on but not when applying gas pedal. Battery gauge only reads half full although fully charged. Took of brake to release the cart and still a no go. Brake does not release when switched to tow. Brakes switch not getting 48v when pedal applied as well. Has a reed bypass. Kids were riding it pretty ruff around the neighborhood (dirtroads) before it happened. No modifications. Any help or suggestions would be greatly appreciated.
