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 dash. The horn does not work and
the battery condition meter does not work. Battery voltage travels from the battery, through the controller and the key
switch. The test below will verify that there is battery voltage at the battery, the controller, the main harness, and the
key switch. Make sure that the battery is fully - charged and connected properly. You can also refer to the wiring
diagram on page 11. If the batteries will not charge, go to “Scenario 2: Batteries will not charge.”
If you are unsure of the correct way to measure
voltage or resistance, refer to Appendix A and B in this manual
before proceeding.
Check Battery Voltage at the Battery pack.
1. Remove the battery pack.
2. Measure voltage across the two inside terminals on the battery
pack. See figure 15.
• 24 - 29VDC (or battery voltage on pack?) - Go to the next step.
• More than 22VDC on pack? - Try to recharge the batteries.
Load test and replace if necessary.
• 0VDC? - Replace the battery pack.
Check Voltage Into the Controller.
3. Make sure the battery pack is installed.
4. Remove the two thumb screws directly below the seat to remove the
controller cover.
5. Measure voltage across the red B+ and black B - wires on the controller.
See figure 16.
• 24 - 29VDC (or battery voltage?) - Go to the next step.
• 0VDC? - Check the 35A fuse for continuity, battery harness for
continuity. Replace as necessary.
Check Voltage Out of Controller.
6. Make sure the red B+ and black B - wires are connected to the controller.
7. Remove the red M+ and black M– wires from the controller.
See figure 17.
8. Measure voltage across the M+ and M– terminals of the controller.
• 24 - 29VDC (or battery voltage?) - Go to the next step.
• 0VDC? - Replace the controller.
Check Voltage at Main Harness.
9. Measure voltage across pin 1 and pin 2 of the XLR port on the tiller.
• 24 - 29VDC (or battery voltage?) - Go to next step.
• 0VDC? – Check the tiller fuse for continuity. No continuity? –
Replace the 3 amp fuse. Refer to the wiring diagram on page 11.
Continuity? - Go to the next step.
10. Open the dash.
11. Disconnect the red key switch harness from the console board (7).
12. Measure voltage across the two pins of connector (CN2). Refer to the
wiring diagram on page 11.
• 24 - 29VDC (or battery voltage?) - Check continuity across the
key switch. No continuity? – Replace key switch.
Continuity? - Replace the console board.
• 0VDC? - Replace the main harness (5).
