Circuit Operation

WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.

Battery voltage is supplied to the AC/DC power outlet control module from the 25-amp AC/DC INV fuse located in the underhood fuse block. The AC/DC power control module is grounded directly to the right rear D-pillar. When the ignition is turned ON, ignition voltage is supplied to the 120-volt power receptacle using the ignition 3 voltage circuit. When a 120-volt AC powered device is plugged into the 120-volt power receptacle, with the ignition ON, the normally open plug inserted switch, located internally in the 120-volt power receptacle, closes. The AC/DC power outlet control module detects an ignition voltage signal on the 120 VAC Inverter control circuit and the AC/DC power outlet control module enables the 120 AC volts to the 120-volt power receptacle.
