IQ PLUS CHARGER (ONBOARD)
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 vehicle has not been driven since the last charge cycle
and the batteries are fully charged, the onboard computer will not perform a self-diagnostic test. The
charge cycle will begin and the ammeter will not drop to zero. 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. Connect the AC power supply cord to a 120-volt AC, 60-hertz, single-phase outlet. The charger relay
should not close immediately, but should close with an audible click after a delay of 2 to 15 seconds. 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 9-2.
2. 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 9-2, Page 9-3) and that the internal charger wiring is correct
(Figure 9-3, Page 9-6).
