Working on a 2002 EZGO TXT PDS golf cart for lady who's son tried to fix it. Brought to me with batteries put in wrong and other problems and the golf cart is not running. Anyway, I bypassed reed switch but can't get reverse buzzer to work to get in test mode checked buzzer off of cart and works. Microswitch in pedal box good and have 36 volts to solenoid. Key switch is sending power to solenoid. Will a bad controller keep the solenoid from engaging on PDS golf cart? I unplugged wire to controller from pedal box and ohm out switch-(good) when the throttle pedal is pressed.
