110V AC Outlet

[CaddyDaddy]

I have a 2019 Interstate Grand Tour. Three 110V outlets ( 2-TVs and 1 above cab) quit working sometime last night. The 3 outlets are labeled "Inverter Circuit". I had a 1500W thermostat controlled ceramic heater, plugged into the outlet where the front TV plugs into. I'm on shore power. I checked the all the breakers in the service panel (under the back roadside seat). They were not tripped. Nevertheless, I flipped all the breakers off then on again, but still no juice in the 3 outlets.

I looked at the electrical schematics and noticed there's what appears to be some kind of fuse (maybe 15 amp) between the outlets and 20 amp breaker in the breaker panel. This is definitely the Inverter Circuit on the schematic diagram. There are no faults on the Magnum Inverter Panel (Don't know if that's relevant since I'm on shore power).


QUESTION: WHERE THE HELL IS THAT FUSE LOCATED SO I CAN REPLACE IT? What secret panel is it behind?

---Please post a picture if that will help me locate the spot I need to be--

Appreciate any assistance in regards to my problem.


Thanks////CADDYDADDY

My Interstate is far different from yours... But my 120 V outlets are all protected by the GFCI on the first outlet in the circuit. Check all 120V outlets to make sure that one of them does not have a tripped GFCI button.

When you're on shore power the inverter passes shore power through to the inverter branch but that branch is still protected by a breaker or fuse. I was understanding the newer models use a breaker rather than a fuse, but either way it is located on the inverter. search online for the inverter manual it will provide guidance on the fuse/breaker. Sorry I could not be more helpful.

Your first mistake was in plugging a ceramic heater into that outlet. The 2 TV outlets and the outlet over the cab for the DVD player are intended only for light loads such as TVs, chargers, and the like. The manual and the dealers should make this clear, but they do not.

I plugged in a heavy-duty (12 awg) extension cord in the curb-side outlet in front of the couch and ran it forward, under the galley in my GT. I installed a rework box in the end of the galley counter by the sliding door, cut and stripped the cord end, and installed an outlet. I did this so I could run a ceramic heater there without using a loose extension cord.

Check this thread, there is a very small circuit breaker on top of the magnum. I did the same thing defrosting the windshield with an electric heater. It seemed like a good idea at the time

Thanks for the advise from everyone. Ok, from what I gathered from your responses, the fuse is on top of the inverter or very close to it.

QUESTION: Where’s the magnum Inverter located in my 2019 Interstate Grand Tour?

Thanks

Under the roadside jump seat. Raise the seat part about halfway and you will see a wire mesh with an opening. The breaker is on the top of the inverter under that opening.

Found the breakers ....1 20amp and 1 15amp. Reset and wallow! Everything back to normal. Thanks everyone especially Pahaska and Getridaone.

Attached the picture for future reference.

I learn quite a bit from these forums. I took a look at the schematics in the 2019 Grand Interstates. The 3 outlet picture below. It does show the breakers. but it says the Inverter is 840W.


Then I looked at my 2020 IS 19 schematics. The two outlet picture below. It does not show breakers but a 30A transfer switch and a 2000W inverter.

All of Airstream specs say these have 1000W inverters. Correct schematics would be nice.
