Re: No Go EZGO
Place DVM test leads between B- and M- on controller.
Should have Full Battery Pack Voltage when solenoid first clicks. (If not, something is wrong in the high current cables, connections and/or solenoid contacts you say are good.  )Slowly press pedal to floor. Voltage should drop to near Zero. If so, check motor. If not, controller or throttle input to controller is bad. |

Re: No Go EZGO
I think your throttle input is within range, so it looks like the controller is bad.

 You've got continuity through motor, f/r and cables or you would not be getting full pack voltage between B- and M- The ITS is telling controller to turn on the MOSFETs. Controller isn't turning on the MOSFETs. ------------ I see I'm late - As usual. Last edited by JohnnieB; 06-05-2012 at 09:08 AM.. Reason: Added comment |
