Circuit Operation

WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

Pressing the 115 volt power outlet switch applies battery positive voltage to the switch indicator lamp and to the inverter relay, activating the relay. The now closed contacts of the relay complete the circuit providing battery positive voltage to the AC/DC power control module. The module converts the 12 volt DC input to the 115 volt AC output provided at the 115 volt power outlet.
