CartManager XD Field Technician Guide Page 18
The symptoms of battery charge malfunction will differ depending on the type of charger in your particular
CartManager XD:
LEDs - the charger has three LEDS; red, yellow and green, for each of the batteries in the CartManager XD. Only
one of these LEDs should be illuminated at a time.
Red – indicates a short circuit, blown inline fuse, reverse polarity (charger hooked up backwards to the battery),
or battery voltage is below 4 volts or above 18 volts. If the red LED is illuminated while the battery is
connected, immediately disconnect from the AC power and check the battery connections. The red LED will
also illuminate if a battery is not connected to the DC battery leads.
Flashing Red – indicates damaged temperature sensor in that bank. This bank will not charge. (Not in older
model)
Flashing Red and Green – indicates possible damage to battery. Load test and replace if necessary. (Not in
older model)
Yellow – indicates the battery charger is in bulk charging mode. This LED will be on until the battery is over 75%
charged.
Flashing Yellow – indicates the battery charger is in bulk charging mode. This LED will continue to flash while
the battery charges from 75% to 95%.
Green – indicates that the battery is over 95% charged and is being maintained. Once the battery reaches full
charge, the green LED will stay illuminated until the charger is unplugged.
Flashing Green – indicates the battery charged, is in maintenance mode and ready to use. (Not in older model)
Red and Green – indicates that temperature switch inside charger has blown or battery is below 4 volts and
should be replaced.
Inline fuses – inline fuses near the terminal end of each positive (red) DC lead serve as protection from extreme
voltage surges or lightning strikes. If a fuse blows, replace it with the exact type and rating of the original fuse.
Improper battery connections will normally not cause a fuse to blow since this is handled by the charger’s internal
circuitry.
Note: that the charger cannot charge a battery that is damaged or has been discharged to less than 8 volts.
Note: For the MK330, many older model XDW CartManagers contain the Minn Kota MK 330 charger, which does
not have any of the flashing lights indicated above.
