Troubleshooting
The BCDi320 is designed to provide years of reliable service and to auto-recover in the event
of an operational failure. In the event of malfunction, the unit is fitted with eight LED indica-
tors and an audible alarm to help diagnose the cause of the issue. Below is a list of potential
issues, and how to repair them.

No Input Power Detected
The charger is not detecting any Input power. Using a
multimeter, check that the power source is working.
Check that the input fuse hasn’t blown. If the fuse is open,
replace it with the recommended fuse listed on the label
and reconnect to power. If the I/P LED still does not glow,
then there is likely an internal failure and the charger will
have to be returned for service.
Low Input Voltage Indication
The charger has detected that the input voltage has
dropped below the minimum level needed for normal
operation. The charger will shut off and wait for the
voltage to recover.

Charger Over Temperature Indication
The charger has detected that its internal temperature
is above safe operating limits. The charger will shut
off until the temperature has returned to normal limits.
If this happens frequently, the charger may need to be
remounted for better air circulation.
Battery Over Temperature Indication
The charger has detected that the battery is too hot to
safely charge (>43°C/110°F) and shut off. The charger
will automatically reconnect when the battery cools to a
safe temperature (<32°C/90°F). If this happens frequently,
particularly in relatively normal ambient temperatures,
the battery is likely damaged or defective and should be
replaced.
