I recently had a passenger in the rear seat try and use the 110V outlet in the rear of the console to charge their phone and the unit wasn't working properly (Yes I know about the 150W limit).
I tested the outlet later that day and found it to be intermittent and also there was no indication that the ground pin was connected to anything as my test gear indicated an open ground even when it saw power across the hot & neutral pins.
I mentioned this to the service advisor but was told they don't "test" the ground only the hot & neutral connection.
In any case they said they were going to order a replacement module and it was installed yesterday. The power looks like it is working but I still do not see any ground connection on my test gear.
Does anyone have access to the wiring diagram for the 110V outlet and can tell me what, if anything, the ground pin should be connected to?
I have owned and installed inverters before (in boats) and the grounding pin is alway connected to the boat's ground (Chassis common) and have showed up in testing. I don't want to just rip this apart to find out it is "by design".
As a point of information the chassis ground is typically the negative connection of the 12V system and the neutral of the 110V power outlet is also connected to this same ground.
Here is a link to a typical inverter and the grounding information can be seen on pages 6-8
