The charging (DC) cord is equipped with a polarized connector which fits into a matching recep-
tacle on the vehicle.
If vehicle it to be charged with a non E-Z-GO charger, refer to the instructions supplied with the charger.
UNDERSTANDING THE CHARGER
Plugging the charger into the vehicle’s charger receptacle will lock the vehicle out of operation. When the charger is
plugged into the vehicle’s charger receptacle, the charger will automatically turn on and the charger’s LED and the vehi-
cle receptacle’s LED will start flashing GREEN to indicate the batteries are charging.
Once a minimum battery voltage of 2 volts per cell (Vpc) is reached, the charger’s output current will change from a full
current charge to the trickle rated charging current. The length of charge time will vary by how depleted the batteries
are, the input AC voltage, and/or charger ambient temperatures. The charger’s LED will give a SHORT flash if the
charge is less than 80% and a LONG flash if the charge is greater than 80%. If the charger’s LED is a steady GREEN
the batteries are fully charged and the charger may be unplugged, although not necessary. The charger may be left
plugged in for long periods of time to maintain the batteries charge level.
If a fault occurred anytime during the charging the charger’s LED will quickly flash RED. The specific fault is indicated
by the number of RED flashes that occur, there will be a pause and then the flashes will repeat again. There are several
possible conditions that will generate errors. Some errors will require human intervention to first resolve the problem
and then reset the charger by unplugging the DC cord from the vehicle.
If the AC voltage is interrupted and restored, the charger will turn back on automatically.
LED Operation Codes
• SHORT GREEN FLASH = less than 80% charged
•
LONG GREEN FLASH = more than 80% charged
• SOLID GREEN = 100% charged
• RED FLASH = fault code
LED Fault Codes
• RED FLASH: Light turns on briefly, but does not flash after that - check for valid AC voltage.
• ONE RED FLASH: One flash, a pause and then again one flash and a pause - Charge Enable Fault: poor con-
tact in the DC connector or dirty contacts or Battery Temperature Fault: battery temperature is greater than 122°
F (50° C) or less than 14° F (-10° C).
• TWO RED FLASHES: Two flashes, a pause and then again two flashes and a pause - Battery Voltage Fault:
Battery pack is less than 48.0 Volts or more than 67.2 Volts. Battery pack is too discharged or over charged for
the charger to work.
• THREE RED FLASHES: Three flashes, a pause and then again three flashes and a pause - Battery Charge
Time-out: Charge time exceeded 24 hours. This may indicate a problem with the battery pack or that the charger
output current was severely reduced due to high ambient temperatures.
• FOUR RED FLASHES: Four flashes, a pause and then again four flashes and a pause - Battery Fault: Charge
time exceeded. This indicates a problem with the battery pack voltage not reaching the required nominal level
within the maximum time allowed.
• SIX RED FLASHES: Six flashes, a pause and then again six flashes and a pause - Charger Fault: An internal
fault has been detected. If this fault is displayed again after unplugging the charger’s DC power cord and plug-
ging it back in, the charger must be taken to a qualified service center.
