Battery Charger Fault Codes

(S/N 030000199 to 030000225 & S/N 030000236 to Present)
If a fault occurred during charging, the red "Fault" LED will flash
with a code corresponding to the error. Refer to the table follow-
ing for the flash codes and their removal.
Flash(s) Fault
1 Battery voltage high
2 Battery voltage low
3 Charge time-out
4 Check battery
5 Over-temperature
6 QuiQ fault
5-14
Table 5-10. Battery Charger Fault Codes (Delta-Q)
Auto-recover - Indicates a high battery pack voltage
Auto-recover - Indicates either a battery pack failure, battery pack not connected to charger or battery volts per cell is less than 0.5 VDC. Check the bat-
tery pack and connections
Indicates the batteries did not charge in the allowed time. This could occur if the batteries are a larger capacity than the algorithm is intended for or if the
batteries are damaged old or in poor condition.
Indicates the batteries could not be trickle charged up to the minimum voltage per cell level required for the charge to be started.
Auto-recover - Indicates charger has shut down due to high internal temperature
Indicates that the battery will not accept charge current, or an internal fault has been detected in the charger. This fault will nearly always be set within
the first 30 seconds of operation. Once it has been determined that the batteries and connections are not faulty and fault 6 is again displayed after inter-
rupting AC power for at least 10 seconds, the charger must be brought to a qualified service depot.
