STATUS LED ERROR CODE TABLE
There are three status lights (LED's) on the charger name plate. These LED's normally indicate the current
operating state of the charger. If all three LED's are flashing, it indicate an error has occurred in the
charging cycle. See the table below for an explanation of the error codes:
Note: If only the 100% LED is flashing and all others are OFF then the charger has exceeded its maximum charging
time and shut off before the batteries were fully charged.
This could be a result of:
•
Defective battery or batteries
•
Excessively discharged batteries
•
Oversize batteries

* - In many cases fault 1 will only be displayed for a short amount of time and then the charger will attempt to restart.
Typically, the fault will repeat 8-times and then the charger will start the boot up process with the 50% light on. If the
charger cannot restart then the fault loop will start again, repeating the fault 1.
This fault could be a result of an open connection between the charger and batteries, an open connection on one or more
of the battery cables, or an open connection internal of the charger.
Before replacing the charger, confirm all battery wiring is good.
