Was there a very large drop in line voltage?
Was charging initiated immediately after the unit was just charged? The charger may saturate faster than the firmware can compensate in this case.
Were locks or extraneous loads left on? Error Code 02 Hex in the error list. ERROR 103
Charge Fault
Charging current feedback value was high during trickle charge.
Check FREQ FDBK 0 signal of the On Board Control port on sheet 5 Location B 9 of the CPU schematic.

ERROR 105 Charge Fault
The charger has been operating at full charger output for more than 15 hours.
Was the unit calibrated properly? Is the line voltage low?
Was the battery voltage below 110 volts before the charge was initiated?
Were the batteries discharged to less than 108 volts? If so a few charge and run cycles may be needed to rejuvenate them.
Error Code 05 Hex in the error list. ERROR 106
Charge Fault
Charge current feedback value was zero. Check FREQ FDBK 0 signal of the On Board Control port on sheet 5 Location B 9 of the CPU schematic.
If a voltage is developed across AMX1-A3-R1 when the unit is first plugged in, the feedback circuitry is defective, otherwise look for a faulty connection or a charge board failure.
Error Code 06 Hex in the error list. ERROR 107
Charge Fault
Charge clamp voltage was exceeded at zero charge current demand.
Check CHARGE SCALE SELECT signal of the Charger and Drive Control port on sheet 4 Location D 8 of the CPU schematic.
