Electrical Problem

[loveallme]

I have a 2009 Sportcoach Legend.
It has a ME2012 inverter with 2-15 amp output circuit breakers with 30 amp fuse.
It has 2 GFI outlets 1-kitchen which controls one side outlets, 2-bathroom that controls other side.
At pedestal, 50amp shore power has the expensive progressive surge protector, checks out fine no issues at pedestal.

Issue:
Bathroom GFI tripped along with 1 of the inverter's 15amp breakers. I Pushed inverter breaker that allowed the bathroom GFI to reset. Within 12 hours it happened again. This time the inverter breaker seems ok but GFI won't reset. Checked the main breaker box under bed and all breakers test fine and are working properly. Checked all lines coming into the GFI and have no power zero on all lines. Checked all dead outlets and no power zero coming into all dead outlets. Checked under bed to trace bathroom GFI breaker line to determine where it goes from main breaker and appears to go to inverter and out into the coach. In rear bedroom there appears to be two outlets that are directly connected not on daisy chain, one works but the other does not. Not sure where the break in power could be occurring. Appears the inverter is working properly but did a reset just in case, still no power to bathroom GFI or side of RV. Any ideas would be most appreciated. Thanks Kelasn

Weak point in the system is the GFI it's self...I would change it first.

Welcome to iRV2.


Key words I see are " inverter breaker seems to be ok " and " no power to the bathroom GFI "

You have to be sure there is power to the circuit , out of the inverter, either by testing the breaker and wire at the inverter , or by pulling the GFI out of the wall to check the wiring for power; not just probing the outlet.

Check for 120volt power to the fridge , it could be daisy chained from the GFI and many fridges with ice makers will trip the GFI if the ice maker needs defrosting . DON'T ask how I know this.

Another note. Many replacement GFIC outlets will have different layout for hooking up , " Line " and "Load " wires , so mark all wires before you disconnect, and compare the markings on the rear of the original and replacement outlets.

My guess is that you have more GFIs than two. The others are scattered around and are not reset able.

Before you start throwing money around.......

The patio outlet? Is it working? (Plug a test device in, Light (I have night lights for that) Three Lamp Tester (Got those too) Fan, Trouble light, Portable Radio.. anything that eats 120vac.
IF it is not powered,, then odds are it draws power via the tripped GFCI.


Now.. unlke the majority of crappy RV outlets these are often decent outlet assemblies mounted in a box. With a weather cover not all that well sealed (I recently re-sealed mine.. Just because). If the caulking cracks,, Rain can infligrate and Pop Goes The GFCI.

Usually when this happens you replace the patio outlet, clean and dry, re-seal and you are good for another decade or so.

Do you have a tripped "output circut breaker" on the inverter itself?
(My inverter has 2 but some inverters have only one).

My ice maker was my problem, when it filled it would trip the gfci in bathroom. I would unplug ice maker and see if the problem goes away.
