SCENARIO 1: TURN THE KEY TO THE ON POSITION AND NO POWER
Put the key into the key switch and turn to the on position. There is no power to the control panel. The horn does not work
and the battery condition meter does not work. Battery voltage travels from the batteries, through the controller and the
key switch. The test below will verify that there is battery voltage at the batteries, the controller, the main harness, and the
key switch.
Make sure that the batteries are fully-charged and connected properly. Refer to the battery connection diagram inside the
battery pack. You can also refer to figure 11 on page 10. If the batteries will not charge, go to “Scenario 2: Batteries will
not charge.”
Check Battery Voltage at Battery Pack.
1. Remove the battery pack.
2. Measure voltage across the two outside terminals on the connector.
See figure 12.
• 24VDC (or battery voltage?) - Go to the next step.
• More than 16VDC? - Try to recharge the batteries.
Load test and replace if necessary.
• 0VDC? - Check main circuit breaker (1) and battery
harness (4) for continuity.
Check Voltage at Power Harness.
3. Remove the two gray floor panels by pushing them up from
the underside of the scooter frame.
4. Remove the four screws fastening the floor shroud.
5. Disconnect the power harnesses (5) from the controller.
6. Reinstall the battery pack.
7. Measure voltage across the red B+ and black B- wires.
See figure 13.
• 24VDC (or battery voltage?) - Go to the next step.
• 0VDC? - Check power harness for continuity.
Replace as necessary.
Figure 13.
Check Voltage Out of Controller.
8. Reconnect the power harness to the controller.
9. Insert the multimeter probes into the terminal with the red
wire (pin 7) and the terminal with the black wire (pin 13)
on the back of the main harness connector (7).
See figure 14.
• 24VDC (or battery voltage?) - Go to the next step.
• 0VDC? - Replace the controller.
Check Voltage at Main Harness.
10. Open the control panel.
11. Disconnect the red key switch connector harness (13).
Figure 14.
12. Measure voltage across the two pins on the male connector
(red and blue wires).
See figure 15.
• 24VDC (or battery voltage?) - Check continuity across the
key switch. No continuity? – Replace key switch.
Continuity? - Replace the control panel.
• 0VDC? – Check the fuse for continuity. No continuity? –
Replace the 1 amp fuse. Refer to Figure 11 on page 10.
Continuity? - Replace the main harness (7).
