NEED HELP! I have chased this problem the better part of 2 days and $300 and had no luck!
When my 2008 HHII 32.5UKTG fifth wheel is plugged into 110V. and the converter is running the ground fault outlet in the kitchen will not trip when the test button is pressed. If the converter is not running and still plugged in the test button works correctly. The converter is on the same circuit as the ground fault outlet which is a good thing.
If I remove the batteries from the system by removing the chassis ground wire or one of the positive post wires with the converter running the outlet works just fine. If appears I have an open ground when the batteries are connected and the converter is running.
I have replaced both the outlet and the converter with no change other than to my bank account.
Do I have to chase every 12v circuit checking for open grounds?
HELP I am at a loss.
The GFCI receptacle needs power to make the test button work AFAIK. So first question is whether, with the converter on and the test button not working, is there any power in that receptacle (plug something in and see)
If no, then turning on the converter is killing the receptacle, they are on the same circuit, so the GFCI is doing its job and there is something not right with the converter wiring.
Disconnecting the battery fixes that. Battery and converter meet at the DC lugs on the DC fuse panel and also via the frame where the 120 and 12v share the frame as "ground"
Swapping the converter to another circuit would stop the problem with that receptacle, but then what would happen if you plugged the RV into shore power that has a GFCI? Trip that? You could try that now at home by running an extension cord into the bathroom GFCI receptacle in the stick house.
My converter 120 only has black and white, no green wire. As suggested above, maybe your white wire is not in the right place.
