TEST PROCEDURES
GENERAL
The charger uses DC battery voltage through the on-board computer to close the charger relay that activates
the charger AC circuit. When the charger is operating properly, there is a 2 to 15 second delay after the DC
cord is plugged into the vehicle before the relay closes. This delay allows time for the DC plug to make a
secure connection with the receptacle before the AC circuit is activated and AC power is supplied to the pri-
mary coil of the transformer. When the relay closes an audible "click" can be heard, and then as power is sup-
plied, the transformer should hum and the ammeter should indicate the charge rate.
WARNING
• ALWAYS WEAR SAFETY GLASSES OR APPROVED EYE PROTECTION WHEN SERVICING THE
CHARGER.
