Electrical woes

My husband live full time in our AS, and after 3 months of glitch free electrical use (minus having to replace the old weak battery and some fuses), all of a sudden our furnace (new) wont click on, the kitchen vent fan, vent lights over the kitchen, and electric jack no longer work. We have replaced every fuse, checked with aluminum foil to see which circuit it is (no use) that could be bad, and come up with nothing. We are about to have an RV repairman come out, but before they do I am hoping someone could give us some tips, or tell us somewhere else to look for issues. The univolt is working, every other electrical 12 volt outlet and light work, the only thing we've done different is replacing the old battery with a deep cell (which made all the lights way brighter). Does this mean we're going to have to rewire?? Also, we have the service manual for the AS and it looks like all these things are wired close together.

Sounds like you have fuse problem. When is Mr. Fixit coming over?

It is all 12volt

Everything you mentioned is 12volt. The fact that you had major improvement when you put in a new battery leads me to believe your Univolt has a problem and a 12volt fuse along with it. If your testing the system with "aluminum foil" I'd suggest you rely on a repairman with some more experience.

It is a guess, but that vintage Airstream used a fuse panel which had it's fuse clips riveted to the main buss bar. It is not at all uncommon that everything looks good with the fuses but the holders are loose. They are difficult, if not impossible to repair or replace and eventually you may need a new fuse panel, but you might be able to work around it for now.

Here is what I would do prior to calling in the big guns. Buy a single fuse holder, the blade type and some 15 amp fuses. They come with 4" leads on either end. Find a source of 12 volt power which is good, as close to the battery as possible. Hook one end of the fuse holder to that source. Then take the other end (you may need to extend the wire) and touch it to each of the smaller color coded wires which leave the fuse panel. They will all be next to each other, and of various colors, and the same size wires. Those are the branch circuit wires.

I am suspecting that you will find that one or more of them now will do something, like restore your furnace and other lights and fans that are not operating. If that does work, then your fuse panel is in fact more or less toast, but you can use other new single fuse holders to work around the defective individual fuses.

It sounds like you have a problem with more than one circuit. I would think the tongue jack would be on a different circuit.
I would start by checking the battery connections, since the circuits involved has motors. Which draw heavier current than lights.
The next step would be to identify which of the circuits
You can do this by turning everything on in the coach. Then pull one fuse at a time and make notes of what goes off. Unless the owners manual ID's the circuits.
You say you have replaced the fuses. Are the fuses tight in their holders? Are the holders tight to the buss. If you can rotate the clips. They are not tight anymore.
Are there signs of the connection points over heating?
Is the insulation of the wires discolored where they attach to the fuse holder? Another sign of overheating.
Are the wire connections clean and tight where they connect to the fuse holder?
If you have a light that works correctly turned on. Does it go out or get dim when you try to run the exhaust fan?
Is this the original Univolt?
Is the fuse panel in the end of the Univolt?
What is the voltage between the + and - buss in the Univolt?
I believe it is time to upgrade to a new three stage converter and a new MODERN fuse block.
Especially if you are full timing.

Good to know

We have replaced all the fuses, and the univolt is humming, and all other 12 volt lights work, but I will work on the fuse panel and fuse ends next. Thanks for the responses!
I hadn't thought of them all having motors, that's interesting. It is the original from what I've gathered.
We are newbies at almost everything lol, but especially electrical bc this is our first issue we've had since we've bought it (June '13), but does checking the battery connections mean just the wires going from the battery to the univolt?

There is no such thing as a good, 40-year old Univolt.
Please replace it immediately with an Iota DLS-55 or a Progressive Dynamics converter-charger with Charge Wizard.
Only then can you seriously troubleshoot your 12 volt electrical system.
It's the first thing I do when I buy a new, old Airstream. It was even the first thing I did on our 2007 Classic 30.
With you husband living in the Airstream full time, the Univolt is going to cook any battery you put in it.
P.S. Take no reassurance from a "humming" Univolt.

Is online the best place to buy a new power converter? Also is there a certain size/brand that will fit for sure?

Get a Paralax...Look on EBAY and shop the prices...they vary greatly. Get a fuse panel too. You can find great deals on EBAY boat Parts...electrical parts. Or, buy from the best and get any reliable advice from Best Converter

I haven't scheduled an appointment. We are trying to move it ASAP, but we can't move till the jack is fixed. Oh the life...

Can you hand crank the jack?

If not, see if the RV park maintenance guy will help

Progressive Dynamics

Sorry to hear about your problem...electrical problems can be very frustrating. I agree with Ken...I would replace your UniVolt. Ours continued to hum away while cooking the battery. Once that goes...no 12v. Deep cycle battery was probably charged and you noticed an increase in your lights. But a bad Univolt will ruin it as well. We have used Progressive Dynamics in several trailers and our motorhome with the charge wizard. I believe they were all PD9245C's. Easy to install and very reliable. Keep us posted on how you make out. Good luck!

I just posted to a similar thread/problem a few days ago regarding the fuse panel and converter. This seems to be a common problem in Vintage trailers. I had the same issues with my previous 72 Overlander. Hopefully this helps you...

Mine is a 77 Sovereign. Bad connections in the 12v panel caused intermittent outages. I quite easily rebuilt the panel using automotive blade type fuse blocks (found at auto parts stores) and the 50 amp fuse blocks from high end automotive audio systems. It was a clean swap out following the schematic from the Airstream manual to insure proper circuit connections. My trailer came with an Iota DLS-55 amp converter, of which I added the 3 stage intelligent charger to it so as not to fry the battery. Now, all systems and circuits are working flawlessly.

I realize you are on the road right now, so a complete change out would probably not be feasible. However, some of the other posts suggesting you test the individual circuits could get you rolling again. As good as glass fuses and their connections look, often times they are problematic. Before I did my big swap out, I would simply twist the fuse in the holder. This sometimes breaks the corrosion (not always visible) and makes for a better connection. Or pull the fuse and with a piece of sandpaper, rough up the connectors. Changing out fuses to known good fuses is essential also.

The condition of your battery at this point is probably not good.

Good luck!

A before.. and some afters of the fuse panel.
