Hi,
The number of flashes on the controller indicates where the fault lies, please see the list below.
2. Brake lever cut off in contact check brake lever spring, brake levers should
return to position (applicable with electric cut-off levers)
3. Brake lever cut off in contact check wiring connection, inspect for damage to the battery level gauge
4. Throttle not in position check if throttle spring is faulty
5. Throttle failure check throttle connections or replace
6. low voltage recharge battery or loose battery cable connection
7. excessively high voltage measure battery voltage, contact your eZee dealer
8. sensor fault contact your eZee dealer
9. motor incompatibility contact your eZee dealer
10. overheat, thermostat activated allow to cool, reboot system
11. thermostat failure replace controller
12. amps control / controller failure replace controller
No light Power failure check battery, power cables or replace controller
I hope that is helpful.
