I've lost power to our central vac, outlets at the booth and behind the couch, outlet @ entry door, outlet in front of passenger seat as well as the 2 outlets in the basement; one of which supplies the central vac.
Called Tiffin twice; first guy gave me things to check; no help....second guy; was to close to beer time...he was on his weekend already and really had no expertise with the product. Kept telling me I needed 50 amp service!

My GFI is good, I checked all my lights and other outlets and they're good; just the ones listed have lost it. Both on shore power and with the generator running. Both A/C's work. All fuses and breakers are good.

I am assuming they're bundled to a circuit but cant find he junction for that grouping...even with the schematics it does not lead you to a junction.
Help!!! Please.

Check the cfi outlet at the sink and bathroom.

Some have two GFI's. Have you looked for a second. Sometimes , they're hard to find.

GFI somewhere you have missed. Check everywhere, including in the basement. Good luck.....

The GFI was the first thing I checked.
Schematic only shows 1 GFI @ the bathroom sink.
But shows a number of outlets protected.

I spent all day trying to find another...and to find THE junction where the circuit plugs in....Tiffin was really no help. I'll be back at it tomorrow. It's making me nuts!

Check the reset button on the inverter. There may be three reset them all.

You will find that most electrical circuits are daisy chained around the RV. Start at the breaker and be sure there is not a loose connection. Then move on to the first outlet in the circuit and do the same. You will more than likely find one of the extremely cheap 120VAC outlets with a wire missing or burned off due to over heating.

Thanks for the replies guys!
I appreciate it.

I'll try tracing from the GFI in the A.M.

I'm assuming you already checked the main breaker panel. The GFI circuit should cover the bath, kitchen, the outdoor outlet, and the one with the TV connections in the bay. The others should be on regular circuit breaker(s).

On the regular breakers, you have to turn them completely off and then back on again to reset.

Something else to consider, a couple of other posts where GFIs were not passing power to outlets down the chain , even though they were re-set. You need to check the " out " ( load ) side of the GFI with a multi-meter, to be sure it is fully operational.

Wiring , junctions would be on the back of the non-GFI outlets too, power in on one side, power out to the next outlet on the other, test with multi-meter, tighten all connections.
The fellow who said 50 amp service may also have a point, if you are only getting one leg of service from your park pedistal then 1/2 your coach will have no power. The problem your having may be with the park power or your cable from the pedistal to the transfere switch. Have you tried , running the gen set ?
Sorry , just re-read and see you've done this.

On my 34 TGA, I had a similar problem, I found that the power wire under the sofa side slide, in the lower storage compartment, was wired just a little too short, and when slide opened it pulled wire out just enough to loose power.

I checked that plug and it was in place (what a pain to get to it though).

That is what I am thinking it might be and will check the
daisy chain next.
The schematic is showing all that are out are on the same circuit as the GFI so it is a good possibility.
Worked outside the coach on washing and installing a KarGuard II today...will attack the electrical issue tomorrow while it rains here....

GFIs do die so be sure and check it. I just had to replace one in the stick house this week so they do have a lifetime.

We have different coaches however, on mine there are two outlets between the rails in the aft larger storage compartment somewhat hidden by a sliding plastic cover, (approximately 18' by 18"). Those outlets are powered by the central distribution system with the important one coming from CB labeled RR. Mine has two other plugs going into the outlets for a total of three plugs held in place by tie-raps. I don't know where the two lines not feeding the RR go but could imagine at least one feeding the slide and vac. If one of those plugs wiggled loose or wasn't tie-wrapped in place securely you could loose power to stuff with no apparent symptoms at the CB panel or GFIs. It's just a thought and with a flashlight and empty storage area it is relatively easy to check the plugs and receptacles. I think the receptacles may be labeled but don't remember last week not to speak of last June.
Good luck, - and let us all know when you find the culprit.
