14. FAULTS
Figure 14-1: Charger LED States (Faults)
Removing AC power from the charger always clears a fault. If the charger was factory-configured for off-
board use, disconnecting the charger from the battery pack also clears a fault. If a fault cannot be cleared
after taking appropriate corrective action, contact your dealer for troubleshooting and/or service.
