Self diagnostic system, Torq and Quando (Edited revision of manual entry)

The controller is programmed with a self diagnostics system to identify some of the possible causes of the motor failing to run. To use this function, count the number of continuous blinks on the controller box red LED when the fault is present.

Blinks                     Fault                                           Recommended Action

LED on            Function normal
2 times           Brake lever cut-off operating                Check lever return spring, See Brake Cutout.
3 times           Brake lever cut-off operating                Check lever return spring, See Brake Cutout.
4 times           Throttle not returning fully                    Check throttle free movement or for spring fault
5 times           Throttle faulty                                         Check throttle connections and cable, or replace
6 times           Low voltage                                             Charge battery
7 times           Excessive voltage*                                 Measure voltage with multi tester
8 times           Hall sensor in motor faulty                     Replace motor core
9 times           Wrong motor connected*                       Replace
10 times           Overheated, thermostat activated         Will return to normal after cooling down
11 times           Thermostat faulty                                   Replace controller
12 times           Current control fault                               Controller faulty, replace unit

*These faults very unlikely ever to happen.

If there's no readout of any of the above and the red LED on the controller is lit, check the controller function in this way. Operate a brake lever and the LED should first go out, then flash 2 or 3 times in quick succession.   If this doesn't happen, it's possible that the controller is faulty.

Other than the above, the main possibility of failure is a connection fault, either at a connector or just possibly due to a broken cable.   The cable routing diagram below may help you in checking the relevant connection points without having to cut tiewraps to trace cable destinations, and the Wiring page has advice on dealing with any connection fault.

Below is a simple routing diagram for the wiring on the Torq 1 and Quando bikes, but for the fullest details download the eZee Technical Service Manual for all models from my website on this link or from the eZee bike website. Download size: 2.45 mB.
