The Univolt is most likely dead. There are 3 Mallory capacitors and a diode rectifier. If the transformer windings are ok, it can be rebuilt. GALCO electronic supply (in Michigan, great service too) has the parts. The good news: A new converter is cheaper and quieter. And lighter.

The Univolt works just fine once plugged into another outlet... The problem is that the outlet beside the Univolt is dead and I don't know why...

My 2001 Safari had a bad outlet, coincidentally where the converter plugged in. The converter worked fine until I replaced it and plugged in the new three-stage unit. It didn't work.The outlet was one of the special RV outlets where the box, outlet, and cover plate were all one piece. The contacts inside were bent pieces of metal and one of them had broken. When I replaced the outlet, all was well.

Your older trailer may have residential outlets. While they are usually better made, I have had to replace some for making intermittent connections. A suspect area is the ones that you just strip the wires and push them in. I have had the gripper release the wire and it backed out of the outlet.

Thanks Al!

I had suspected the same thing, so I pulled the outlet off the wires and hooked them up to a light bulb. Still nothing.

I can live with the outlet not working... What worries me is that there is potential for a fire if there are bare wires running through the trailer causing the outlet malfunction. Maybe an extreme case, but at any rate, I'd like to get to the bottom of this.

According to the manual, the outlet for the converter in my trailer is wired from the outlet in the front on the road side under the window. Airstream has used the same wiring techniques for years, so maybe yours is wired the same. Pull the closest outlet to the non-working one and see if there are wires that have come disconnected.

So no power to the wires when disconnected from the outlet, be careful on live lines.
Looking at the wiring drawing for 31' rear bath that circuit goes from the #1 circuit breaker, then through the polarity light, then an outlet in the bath, then to a outlet curb side bedroom, then outside outlet, then to street side bedroom outlet, then forward to the univolt outlet. Check the bedroom outlet on street side, should be a little forward opposite side of the outside outlet. If it's got power pull it out and check inside , the push in outlets can have a different wire going in and separate wire going out. They get stacked pushed down into the grooves for contact. If the out going worked loose it could be the problem.
If there were bare wire touching somewhere you'd be tripping the breaker, so probably not the problem. Broken wire is possible but not likely.
Do you have one of those voltage checkers that you just hold on the outside of a wire and it lets you know if there's voltage present?

That's good. Replace the outlet. They go bad too.

Mike ,
The way I read this, "so I pulled the outlet off the wires and hooked them up to a light bulb. Still nothing." Means you did just that, pulled the wires clean out of the outlet, got some bare copper to connect wire to to connect to a bulb, and still nothing.
Just to be sure, you had the rest of the circuit energized when you checked with the light, didn't turn it off to get to wires and forget to reenergize when checking with light.
We all have brain farts.
If so that should rule out a bad outlet.
Joe

To be more clear - I shut off the breakers to the trailer and unplugged it from shore power source. I removed the outlet and attached a light bulb fixture with marettes. I plugged the trailer back in and switched on all the breakers. The light bulb did not turn on. I can confirm that there is no power going to the outlet. I pulled the outlet off the bedroom wall (which, according to the owner's manual is the last item before the wire runs through the ceiling to the Univolt plug). The plug looks different than what I'm used to - normally there are 2 silver, 2 brass and 1 ground on the outlet, but the trailer has just one line (a black nylon(?)-covered wire bundle) that goes into the back of the outlet. Never seen one like that before.

The outlets are wired in parallel. If the "upstream" outlet has power, the Univolt should have power as well. I will take mine apart at the bedroom and the Univolt outlet, and post some pictures. Does the outlet under the credenza (to the right) work as well?

The outlets don't have screws to attatch the wire in them like in a house, instead the wire gets the outer insulation stripped and the three wires still individually insulated get pushed down between some blades that pierce the insulation on the sides of each wire, theoretically it will let you run one continuous wire for the whole length. However more than one wire can be pushed down into those blades, usually up to 3. In which case if they didn't have enough to reach the forward part of the trailer, they start another wire by pushing it down onto those blades. If that's the case the wire leaving to the univolt may have worked loose, causing a break on power distribution. My original wiring had the stop old wire, start new wire, at the last outlet before it ran to the univolt, not 100% sure if that was some kind of standard practice.
The back of the outlet should have tabs on the sides that you just pry up a little to get the back to slide off. Once you see it it'll make sense.
The outlet to the credenza is a separate line. Seems dumb, but if all original, which is likely nobody did rewiring, the univolt shares power with the back half of the trailer. If there is power to a different nearby outlet, you could tap into that for power, push to shove.

Got some pics of what your outlets are probably like.

What it looks like closed on back, just have to pry the side tabs to get back to pop off.

About what it will look like with wires in there, they would be pushed down into the slots you can see, they cut through the insulation. Friction holds the wires in, if there are more than one wire, the first inserted pushes apart on the blades a little, which can make the next wire looser, and possibly work loose.

If you could send a pic of the univolt outlet it might help.

So it turns out somebody has screwed with the electrical at some point! There are 2 plugs which are regular household plugs, as well as the Univolt plug itself which aren't like the ones you describe above. They include the microwave plug and the plug next to the fridge in the front cabin.

I should also note that my sovereign is the "lounge" model, with the 2 couches up front and wicked 8track player in the corner. The layout isn't consistent with either of the layouts in the owners manual, but it's pretty close.

Anyhow, here's a picture of the Univolt plug. This is turning into quite the brain buster!

Did you remove the above receptacle and test the WIRE itself for power?

Have you tested the output side of each breaker for power? A breaker can look good but have failed. Testing is the only way to be sure.
