Battery Warning Light

TEST PROCEDURE 26 – Battery Warning Light
See General Warnings on page 1-1.
1. Reboot the OBC and drive the vehicle a short distance. When vehicle is first driven, the battery warning light
should illuminate for 10 seconds. See Test Procedure 25 – Rebooting the Onboard Computer on page 12-37.
If the battery warning light does not illuminate when rebooting the OBC, proceed to step 2.
2. Turn key switch OFF, place Tow/Run switch in TOW and place Forward/Reverse rocker switch in NEUTRAL.
3. Disconnect the six-pin connector at the OBC.
4. Remove the wedge lock from the six-pin connector housing that is connected to the vehicle wire harness.
Remove the brown/white wire from the connector plug.
5. Using a jumper wire with an alligator clip at each end, connect one alligator clip to the negative post of battery
no. 1 and the other alligator clip to the brown/white wire terminal socket that was removed from the six-pin
connector plug.
6. Install the wedgelock in the six-pin connector housing and reconnect the six-pin connector plug. Place the
Tow/Run switch in the RUN position and the battery light should illuminate. If the light does not illuminate,
replace the battery warning light assembly.
BATTERY WARNING LIGHT
IQ System and Excel System vehicles feature a dash mounted battery warning light (above the steering column) that,
when the vehicle is in operation, indicates low battery voltage or, when the vehicle is being charged, indicates a
charging problem. The battery warning light is controlled by the onboard computer.
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.
