AGS PROBLEM--Ground fault problems

Anyone have a 2017 ARIS Motorhome that has AGS that will work on the first automatic start up, then disable the AGS on it's on for the next need to start the generator?
Then, the next issue is the ground fault receptacle in the bathroom clicks off on battery power, works on shore, or generator power???
Batterys can be fully charged Ground fault will trip??

Hi Dan , with you connected to shore power or with the generator on you would have the AC power you need for the GFI plugs . You didn't mention that you you had an inverter that turns your DC to AC for your plugs .

do you mean an Thor ARIA?

if so, your AGS is a great tool, but the internal setting to Enable it can be overriden if you happen to turn it off manually after it has started, with the TYPE setting as 'RV'... instead the TYPE setting should be changed to 'OTHER', so that turning the generator off will not disable the future runs from the AGS.

The OTHER type setting allows the AGS settings to remain active even if you manually turn off the generator after the AGS has started it.

as for the 'tripping'/dead GFCI outlet/circuit, when on the Inverter, I would check the tightness of all your breakers within your Main panel, as they sometimes become loose after the initial installation from the factory, creating issues where they seem to work some times, and not others.

Also check the tightness of the connections within the outlet itself, if those in the main panel don't seem to be suspect.

Hi, regarding the GFI issue, normally RV AC panel neutral and ground connections must be kept un-bonded (not connected). When on shore power the camp ground electrical system provides the single bonding point to the RV; when running on generator the RV transfer switch should provide the single point bonding connection only when in generator running position; when on inverter (at least with internal inverter transfer switches) the inverter in AC pass through mode, does not bond heutral and ground together; but when the shore or gen AC drops off the inverter supplies AC and its transfer switch then should provide the single point bonding. So perhaps the inverter transfer switch is not providing the neutral ground bond and the downstream GFI trips due to slightly higher currents detected in its ground wire. A good article to read on single point grounding is attached.....if my link works.

me too, but your outlets should work no matter 'which' power source you are getting from... there is no 'difference' since it's simply 120v power.

I imagine you have an issue with a loose wire somewhere... find it.

Thank You Turner,
Appreciate the help from all folks on this forum. Had many RVs in the past 20 years this is first for us on this electric turmoil.
