LED Status Display
The charger has five colored LEDs located on the top
of the charger. The LEDs are used to indicate the
status of the charger during operation. The order of the
LEDs may vary with models, but are labeled to identify
their function. See Figure 7. Convenience port LEDs
and charger LEDs should reflect the same charging
progress. If the LEDs do not match, the charger is not
connected correctly.
NOTE: If center LED illuminates and then flashes
towards the outer most LEDs, disconnect charger B(+)
lead from fuse and wait 10 seconds. Connect
charger's B(+) lead to fuse terminal and retest system.
