Checking the HALL EFFECT SENSORS 

Here are some tips on checking the motor status

Connect the wires as shown in the picture

Sensor Wire Position 

 (1) Make sure there is power in the sensors

Check Supply Voltage

#1 : Positive 

#2 : Negative

1. Turn the throttle on while checking the sensor voltage between #1 and #2

It is not necessary to connect the 3 motor wires

If the Voltage is between  7 volt - 9 volts this good 

If there is no voltage between #1 and #2

check the following 

1. Some cables  are not connected well , For example battery cable or hall effect plug gently test the wires on the hall effect plug to see if they are loose.

2. The speed controller may have failed 

3. There may be a short circuit in the wiring

(2) Check 3 sensor's condition

#3 ~ #5 for sensor's cable

- Check sensor's wire condition, What to know Are there any broken or disconnect??

- Check 3 Sensors Condition

Request Condition: 

1. Turn on the throttle check the three pairs of terminals  2,3   2,4   2,5

2. The 3 motor wires do not need to be connected

3. Rotate the wheel or motor hub while checking the sensor terminals.

Status in Voltage : 

The voltage will change from 0 v to 13 v as the wheel is rotated as the hall effect sensor is triggered 

Condition : Good 

Problems Status:

1. If the voltage does not change from 0v to 13v but stays at 0v or 1v 

The possible problems

-  There is a fault in the hall effect sensor connector check this again

-  One or more of the hall wires is broken  

-  The Hall effect sensor has failed.

2. If all 3 sensor's wires display in 13 volt  ( no change ) while checking

Condition :  The ground wire is broken ( #2 wire )

3. If all 3 sensor's wires display in 0 volt ( no change ) while checking

Condition: The positive wire is  broken ( #1 wire )
