If one GFI is tripped (No working) then I agree nothing will work;
Check to be sure the GFI is Active by plugging a lamp into it.
If the lamp doesn't work then do 1 - 4 repeat.
1) Press rest
2) Check with Lamp
3) Replace GFI
4) Check with Lamp


Note:


No need to install a GFI on everything, The one GFI is most likely wired to trip for all 120v circuits.

On most RV the connection is close to the slide out. Often at a duplex in or close to the inside non-sliding wall. Check to see if there is a GFI wall plug that is tripped. It could be anywhere in the RV and sometimes the circuit layout seems to be without reason. Be sure to check the GFI in the bathroom and also the one in the kitchen. When you find the GFI hit the off button and then reset them, then check your tv for power. GFI's protect everything down circuit against shorts or prone to be wet locations. As sooner or later there may be some leakage at a slide out, it makes sense to have the plug in protected.

The slides are designed to tip and drop when coming out so that when fully extended they will be flush with the floor. When coming back in the bottom will pull in first and cause the top to tilt out until the slide fully closes and the weight transfer back to balanced and the slide properly seals. When the slide is all the way out is it sealed all the way around? If it is then you do not need to adjust. There is alot of weight being balanced at two connecting points under the slide. If it does need to be adjusted you are better off taking it to someone who knows what they are doing.

BINGO - try looking for the GFI - maybe the bathroom - that could very well be your problem.

Can't tell that from the VIN. Only where manufactured. Could have been shipped anywhere.

Try doing a title search at your local DMV. Might turn up something.

First, the GFI runs on house current aka shore power. Make sure you are plugged in! Most GFIs have a light showing power on.

Check your breaker - not a car type fuse - in the fuse panel. GFIs are nothing but a quick-disconnect in case of a short. (Quick description)

You really need a wiring diagram for this. Try and get one online or from the mfg.

Start by tracing back towards power source from GFI. Remove GFI and check for power on the wires. Be careful, it's 120vac house current. If you have power, replace the GFI. If no power, look at the diagram and proceed to the next outlet/GFI on the same circuit. You might have to go all the way to the power distribution panel. Sooner or later you will find the open wire. Might be nothing more than a screw vibrated loose disconnecting the power feed.

Have you done a VOM test on the house lines to the bath from the circuit breaker box? This is important, without the GFI in place, just the bare wire test? If you have voltage from the box to the Bath wires, then your power is correct and the attached outlet needs to be checked for continuity. If no power to the bath from the box, the circuit breaker may be bad, or tripped.

i have seen a meter lie, it shows a good circuit, but when a load is applied the circuit breaks, try a test light to see if the breakers hold
