Default Re: Ez Go Marathon Not Working

Could be a bad motor or a bad controller or a bad throttle or a bad amp delivery circuit or a combination thereof.

Connect a DVM between the controller's B- and M- terminals and press pedal just far enough to make solenoid click. If you read battery pack voltage (about 38.2V when fully charged), the amp delivery circuit is intact.

If you get battery pack voltage, slowly press pedal to floor and voltage should smoothly decrease to zero.

If it doesn't, check the pot-box throttle.

If it does, check the motor.
