Check Procedure 7C—Pin 7
1. Use a multimeter set at 200V DC, insert the red (+) probe of the multimeter into Pin 7 (pink wire).
Refer to the following Note. Connect the black (-) probe to the negative binding post of the battery
pack.
Δ Note:
• Never insert the complete probe into the 9-wire plug for fear of poor contact.
2. When Tow/Run switch is turned on RUN and Forward/Reverse switch is on NEUTRAL, the
multimeter should display a 0V DC voltage.
3. Depress the accelerator pedal slowly, the multimeter voltage should change from 0V to 4.6-5V.
4. If multimeter voltage does not change, the following items must be checked:
4.1 Continuity of wires in harness;
4.2 If the continuity is ok, please check whether the handle brake switch is connected and the wire
connection is correct, if it is abnormal replace the accelerator.
Check Procedure 7D—Pin 6
1. Use a multimeter set at 200V DC, insert the red (+) probe of the multimeter into Pin 6 (red/green
wire). Refer to the following Note. Connect the black (-) probe to the negative binding post of the
battery pack.
2. With key switch turned ON, turn Tow/Run switch to RUN, then the multimeter should display a full
battery voltage (about 48V).
Δ NOTE:
• Never insert the complete probe into the 9-wire plug for fear of poor contact.
3. If another reading is displayed, the following items must be checked:
• Continuity of wires in harness;
• Check whether the key switch operates normally;
• Check whether Tow/Run switch operates normally. Refer to “Check Procedure 4 - TOW/RUN
switch” on page 25.
Check Procedure 7E—Pin 3
1. Use a multimeter set at 200V DC, insert the red (+) probe of the multimeter into Pin 3 (magenta
wire). Refer to the following Note. Connect the black (-) probe to the negative binding post of the
battery pack.
