EXCEL SYSTEM TROUBLESHOOTING: WITH
POWERDRIVE CHARGER
When the batteries receive an incomplete charge because 1) the DC power cord is disconnected, 2) AC power to
charger is interrupted, 3) automatic charger shut-off occurs after 16 hours of operation, or 4) charger malfunctions, the
warning light will indicate as follows:
• The battery warning light will not illuminate if the charge is 90% or more complete. The onboard computer will
retain in memory the amount of charge needed to replenish the batteries and will complete the charge during the
next charge cycle.
• When the charger DC cord is unplugged during a charge cycle, the battery warning light will illuminate and remain
illuminated for 10 seconds if the charge is less than 90% complete but the vehicle has enough power for 60
minutes of operation. This will alert the fleet operator that the vehicle may be used, but that it must be charged to
completion as soon as possible.
• The battery warning light will repeatedly illuminate for 10 seconds, at 4 second intervals, if the charger times out at
16 hours and the batteries are not sufficiently charged. This indicates an abnormal charge cycle. The charger and
batteries should be checked by your Club Car distributor/dealer.
• The battery warning light will repeatedly illuminate for 10 seconds, at 4 second intervals, during a charge cycle (with
the DC plug still connected) if AC power to the charger is interrupted. The light will go out when AC power is restored.
• The battery warning light will flash quickly, after inserting the DC plug, indicating the charger’s voltage suppressor
has failed closed.

The CDM can be used to retrieve from the onboard computer four important items of information that can be useful in
troubleshooting the Excel System vehicle. To access one of these items, the item’s corresponding Function Code must
be selected on the CDM. This is done by pressing the Function Button until the desired function code is displayed
in the window.
See Figure 13-19, Page 13-38 for CDM features. Releasing the button when the desired code is
displayed will display the data. Function codes and corresponding data are as follows:
• F1 – Battery voltage:
• This displays the battery pack’s current state of charge. A reading of less than 48 volts indicates that the batteries
need to be charged. If a reading of less than 48 volts is obtained immediately after a charge cycle, there may be
a problem in the charge circuit.
