Testing Guide
1.
Brushless Motor Testing
- Keep it in mind that ONLY the black
and red wires are strictly color-coded.
- Motor Hall Chip testing:
--> connect the motor Hall connector (5 fine wires) with the
tester.
--> make sure the black and red wires are properly connected.
--> turn on the tester power.
--> slowly turn the motor wheel forward.
--> HA(blue), HB(green), HC(yellow) lights should turn on and
off sequentially.
--> Otherwise, there is either loose connection or damaged Hall
chips.
-
Motor Copper Core testing:
--> connect two of the 3 coarse wires (phase wires) with each
other should produce equal resistance when turning the motor wheel.
Otherwise, there is a short circuit within the copper core wiring.
--> connect the 3 coarse wires from the motor to the tester.
--> keep the tester power off.
--> turn the wheel with motor.
--> XA(blue), XB(green), XC(yellow) lights should all be flashing.
--> Otherwise, the corresponding portion is faulty.
2.
Brushless Controller Testing
- Connect the controller Hall connector
(5 fine wires) and the 3 coarse phase wires with the tester.
- Disconnect the speedometer wire from the controller, if there
is any.
- Keep the tester power off.
- Turn on the ignition to power the controller.
- 5V light should be on once the controller is powered. Otherwise,
it's a faulty controller.
- For a 120° controller, Q1-Q6 lights should flash in 3 even
& odd pairs when turning the throttle. And none of lights flashes
if the Hall connectors are disconnected. Otherwise, it's a faulty
controller.
- While for a 60° controller, one pair of the lights won't flash
when turning the throttle. But it will be the one and only pair
of lights which flashes when the Hall connectors are disconnected.
Otherwise, it's a faulty controller.
3.
Throttle Testing
- Connect the 3 throttle/brake testing
leads to the 3 throttle wires on the bike.
- The black and red wires are strictly color-coded.
- Turn on the tester power.
- Throttle works properly if the throttle/brake LED's brightness
increase (as for a normal throttle) or decrease (as for a reverse
throttle) gradually while turning the throttle. Otherwise, the throttle
is deemed faulty.
4.
Brake Microswitch Testing
- Tests the microswitch on the brake
lever which cuts off motor when a brake is applied.
- Connect
the red and green throttle/brake testing leads to the brake switch
wires.
- Turn on the tester power.
- If the throttle/brake LED turns on after connecting the wires,
the microswitch is a CLOSED type.
- In case of a CLOSED type brake microswitch, the throttle/brake
LED should turn off when applying either front or rear brake. Otherwise,
the microswitch is deemed faulty.
- If the throttle/brake LED remains off after connecting the wires,
then turns on after applying either front or rear brake. The microswitch
works properly. Otherwise, it is deemed faulty.
