BATTERY CHARGING
Connect the supplied power cord to the vehicle charger receptacle and to
a properly grounded 120 volt AC supply minimum 20 amp circuit wall
outlet. Charger start and charge time is automatic. The receptacle is
located directly beneath the key switch on the right side of the console.
Charger start and charge time is automatic. The remote LED will be
flashing short green. If this LED is not lit check the AC connection and the
AC source fuse or breaker. If this fails to correct the problem, contact your
Columbia Dealer for assistance.
Charger will automatically turn on and conduct a short self-test and battery
pack test. The LED will flash in sequence and then a trickle current will be
applied to batteries until a minimum voltage is reached.
If the batteries meet the minimum voltage requirements of the charger,
signifying they are serviceable (chargeable), the charger enters the bulk
charging (higher amperage-constant current) stage. The remote LED will
be flashing short green.
NOTICE: If the batteries are excessively discharged, the charger will not be able to
charge the complete set of batteries. The remote LED will be flashing red (see Red
Light Charger Error Codes). It will then be necessary to follow the Special Charging for
Excessively Discharged Batteries.
When the charger has completed approximately 80% state of charge the remote LED will flash
long green as the last 20% of charge is returned to the batteries in the second phase (constant
voltage phase).
NOTICE: You can terminate charging at this point if necessary. The vehicle can be
used, but completing the charge cycle is highly recommended.
A Green LED continuously lit indicates the batteries are completely charged. The charger may
now be unplugged from the AC source. If the batteries will not be used for a length of time,
check monthly for the charge level. It is also acceptable to leave the charger plugged in. The
charger has the capability to test and recharge if necessary.
Repeated “Short Charging”, leaving the charge short of 100% will shorten operating cycle
distance and reduce battery life.
A fault occurring while charging causes the remote LED to flash with a code relaying the error.
Some errors may require repair by a qualified technician and others may be simply transient
and will automatically recover when the fault condition is eliminated and the charger cycled by
disconnecting the AC source for a minimum of 11 seconds.
NOTICE: A Yellow (Amber) flashing remote LED indicates the thermostatic control has
limited the charger output due to ambient temperature conditions. It is still charging,
but at a reduced rate.
