Scenario 1: Turn The Key To The On Position And No Power - Golden Technologies Buzzaround XL GB146 Service Manual

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. Refer to Appendix D on pages 29-39 for troubleshooting flow charts.
NOTE: Make sure that the batteries are fully-charged and connected properly. Refer to the battery connection diagram
inside the battery pack. If the batteries are not fully charged and connected properly, then voltage measurements may
produce faulty readings. Measure voltage across pin 1 and pin 3 on the battery pack to get total battery voltage
(approximately 24VDC). Refer to gure 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 terminals 1 and 3 on connector
4a. See gure 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
harnesses for continuity (4a terminals 1 to 4c and 4a
terminals 3 to 4d).
Check Voltage at Power Harness.
3) Remove the four screws that fasten the controller cover to
the underside of the scooter frame.
4) Remove the cover.
5) Disconnect the power harnesses (5c and 5d) from the
controller.
6) Reinstall the battery pack.
7) Measure voltage across 5c and 5d. See gure 13.
24VDC (or battery voltage?) - Go to the next step.
0VDC? - Check power harness for continuity.
Replace as necessary.
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 7a. See
gure 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 main harness (7b) from the control panel
harness.
12) Measure voltage across pin 3 (black wire) and pin 8 (red
wire) on connector 7b. See gure 15.
24VDC (or battery voltage?) - Replace the control
panel.
0VDC? - Replace the main harness.
