IQ PLUS ONBOARD CHARGER FEATURES
• Charge Interlock
When the AC power cord is inserted into a wall receptacle, the onboard computer locks out the vehicle
drive system. This prevents the possibility of driving the vehicle while the charger is plugged in and
potentially damaging the vehicle and charger.
• Long-Term Storage Charge
IQ Plus chargers are designed to be left connected with AC power to the charger, during off-season or
long-term storage. The onboard computer will automatically activate the charger every 15 days. To
return the vehicle to service, disconnect the AC cord from the wall outlet, wait 15 seconds and then
plug the AC cord back in. The charger will activate. Allow the vehicle to complete one full charge cycle
before putting it into service.
BATTERY WARNING LIGHT
IQ Plus 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 charg-
ing problem. The battery warning light is controlled by the onboard computer.
When the batteries receive an incomplete charge because 1) AC power to charger is interrupted, 2) automatic
charger shut-off occurs after 16 hours of operation, or 3) charger malfunctions, the battery warning light will
indicate as follows:
•
The battery warning light will not illuminate if the charge is 90% or more complete. The onboard com-
puter will retain in memory the amount of charge needed to fully replenish the batteries and will com-
plete the charge during the next charge cycle.
•
When the charger AC 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 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 CHARGE CIRCUIT
For vehicles with onboard chargers, the charge circuit consists of the following components:
•
onboard charger
•
onboard computer
•
batteries
The 10-gauge black wire from the charger connects to the onboard computer black lead wire. The 6-gauge
black wire (also on the controller B– terminal) goes through the onboard computer and connects to the neg-
ative (–) post of battery no. 8
(Figure 6-5, Page 6-11)
. The 10-gauge red wire of the charger is connected to
the positive (+) post of battery no. 1 for Turf 2/252, Carryall 2/252 and XRT 900 vehicles, and the large post
of the solenoid (battery side) for Carryall 6, Villager and TransPorter vehicles. The 18-gauge gray wire from
the charger connects to the onboard computer
(Figure 6-2, Page 6-3)
