1. Accessory DC/AC Power Inverter Module Always OFF 2. Accessory DC/AC Power Inverter Module Always ON

The accessory DC/AC power inverter module converts 12 V direct current (DC) battery voltage to 110 V at 60 Hertz (Hz) alternating current (AC) in order to operate AC powered devices. The accessory DC/AC power inverter module provides up to 150 watts of power. The accessory DC/AC power inverter module is connected to a chassis ground circuit and receives fuse protected battery voltage.

The accessory power receptacle - 110 V AC has an internal switch, that detects when an AC powered device is plugged into the receptacle. When the ignition is ON and an AC powered device is plugged into the accessory power receptacle - 110 V AC, the normally open switch in the accessory power receptacle - 110 V AC, closes. When the accessory DC/AC power inverter module detects the voltage from the accessory power receptacle - 110 V AC switch, the inverter module begins to supply 110 V AC to the accessory power receptacle - 110 V AC after a 1.5 s delay.

For equivalent regional tools. refer to Special Tools .

Removal Procedure

  1. Remove the auxiliary power outlet fuse from the fuse block.
  2. Remove the receptacle: Look into the receptacle. There are two 3 mm (0.11 in) tab windows 12 mm (0.47 in) from the front of the receptacle. The EL 42059 Remover pushes the plastic latches from these tab windows and the receptacle can be pulled straight out. Place one side of the "T" portion of the EL 42059 Remover into the tab window. The EL 42059 Remover will not fit straight into the receptacle. Angle the EL 42059 Remover slightly for insertion into the receptacle. Insert the other side of the "T" into the opposite tab window. You must move the EL 42059 Remover handle toward horizontal to engage the other tab window. Use the EL 42059 Remover to pull the receptacle straight out.
  3. If EL 42059 Remover tool fails to release the lighter socket from the retainer, perform the following alternate method: Insert a small grinding tool with a cutoff wheel into the socket. Remove the plastic latches in the 3 mm (0.11 in) square windows. Use the EL 42059 Remover as directed above to remove the socket.

Installation Procedure

  1. Route the connector through the retainer. Align the accessory power receptacle retainer to the slot in the opening.
  2. Install the retainer by pressing into place fully seated.
  3. Connect the electrical connector to the receptacle.
  4. Align the tabs on the receptacle to the slots in the retainer. Install the accessory power receptacle by pressing into place until fully seated.
  5. Install the accessory power receptacle fuse.

12 Volt Power Outlet Receptacle Description and Operation

The 12 V accessory power receptacles and cigarette lighter are supplied B+ when the ignition is on or in the accessory position.

110 Volt Power Outlet Receptacle System Description

The alternating current (AC) accessory power outlet system consists of the accessory DC/AC power inverter module and the accessory power receptacle - 110 V AC. The accessory DC/AC power inverter module converts 12 V direct current (DC) battery power to 110 V at 60 Hertz (Hz) AC power to operate AC powered devices. The accessory DC/AC power inverter module provides up to 150 watts of power. The accessory power receptacle - 110 V AC provides the usual connection for AC powered devices.

110 Volt Power Outlet Receptacle System Operation

The accessory DC/AC power inverter module receives fuse protected battery voltage and is connected to the 12 V electrical system ground. The accessory power receptacle - 110 V AC has an internal switch, that detects when an AC powered device is plugged into the outlet. When the ignition is ON, and an AC powered device is plugged into the accessory power receptacle - 110 V AC, the normally open switch in the accessory power receptacle - 110 V AC, closes. When the accessory DC/AC power inverter module detects the voltage from the accessory power receptacle - 110 V AC switch, the inverter module begins to supply 110 V AC to the accessory power receptacle - 110 V AC after a 1.5 s delay. The accessory AC power system is protected against circuit overload and circuit shorts to ground.

110 Volt Power Outlet Receptacle Isolation Fault Protection

The accessory DC/AC power inverter module contains a ground fault circuit interrupter. The ground fault circuit interrupter monitors the 110 V circuit for a short to vehicle chassis ground. If a 110 V AC short to ground is detected, the accessory DC/AC power inverter module will turn OFF. The module remains OFF, until the AC powered device is unplugged from the outlet, and then plugged into the outlet after a 3 s delay.

110 Volt Power Outlet Receptacle Overload Shutdown

The accessory DC/AC power inverter module will turn OFF if the current in the 110 V circuit is greater than 3.8 A for 1 s, or 2.5 A for 10 s. The module will turn ON again, when the AC powered device is unplugged from the outlet, and then plugged into the outlet after a 3 s delay.

110 Volt Power Outlet Receptacle Internal Shutdown

The accessory DC/AC power inverter module will turn OFF if the B+ supply voltage is greater than 16.5 V or less than 11 V. The module will also turn OFF if the device temperature is greater than 85°C (185°F). The module will turn ON again, after the shutdown condition is corrected, and the AC powered device is unplugged from the outlet, and then plugged into the outlet.
