IQ PLUS CHARGER (EXTERNAL)

CHECKING BATTERY CONDITION WITH AN EXTERNAL CHARGER

Read DANGER, WARNING, and CAUTIONS beginning on page 4.
It is common practice for technicians to check the condition of a set of batteries after they have been charged
to ensure they have received a complete charge before the vehicle is used. With the IQ Plus vehicles, this is
not necessary; the onboard computer controls and monitors the charge cycle. If any problem occurs during a
charge cycle, the battery warning light, located above the steering column in the center dash panel, will illu-
minate intermittently.
If the battery warning light is illuminated after a charge cycle, refer to the troubleshooting chart in the mainte-
nance and service manual appropriate for your battery charger. If you do not have this publication, contact
your Club Car representative. If the specified test procedures identify no problems, plug the DC cord into the
vehicle and let it charge until the charger shuts off automatically. If a problem is found, correct it and then
charge the vehicle. Normal voltage near the end of a charge cycle should be approximately 59 to 63 volts DC.

START CHARGE CYCLE

1. Disconnect the DC plug from the vehicle charger receptacle.
2. Wait 20 seconds, then reconnect the DC cord to the vehicle receptacle. See following NOTE.
NOTE: The charger will not operate unless a delay of approximately 20 seconds is observed.
3. Monitor the ammeter for the charge rate. If the batteries are close to being fully charged, the charge cycle
will begin and the charge current will begin to taper within a few minutes.

TESTING CHARGER OPERATION

1. With the DC plug disconnected from the vehicle charger receptacle, insert the AC cord into an outlet. The
charger relay should NOT close. A multimeter set to volts DC and connected across the DC plug positive
(+) and negative (–) pins should indicate zero volts. No transformer hum should be heard.
2. Disconnect the AC cord from the wall outlet and connect the DC plug to the receptacle. The charger relay
should close with an audible click after a 2 to 15 second delay. See following NOTE.
NOTE: Monitor the charge cycle to make sure the charger turns off properly. If the charge cycle is inter-
rupted, and the batteries are less than 90% charged, the battery warning light will illuminate inter-
mittently. See Battery Warning Light on page 8-2.
3. If the charger does not operate exactly as described above, refer to the wiring diagram and make sure
that the vehicle is wired correctly (Figure 8-2, Page 8-3) and that the internal charger wiring is correct
(Figure 8-5, Page 8-9).
