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 5-2.
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 5-2, Page 5-3)
and that the internal charger wiring is correct
(Figure 5-6, Page 5-9)
