Protecting the Breakway & Jack Wiring

Once you get the repairs made to the wiring, you might want to protect the wiring to avoid this happening again...we did this on our rig. We bought clear flexible plastic tubing, slit it on one side and put it over the wiring for both the jack and the breakaway wires so that it doesn't rub against the propane tank cover, etc...then wrapped electrical table every 4 or 5 inches to keep it in place. Not taping it completely allows water to escape should it get inside the tube...

In addition to doing what TB Rich suggested, you might want to add plastic mounding to the bottom of the propane cover where it rests on the trailer frame. This will increase the space available for the electrical conduit and reduce the chances of the cover rubbing against the wires in the future.

That's a service type battery,so look closely at the cell cap(it does come off) make sure that the shorted wire did not burn a hole thru the cap. WHILE you are there check the water level under both caps and fill to the bottom of the openings with DISTILLED WATER ONLY. If there is a hole burned thru it will need to be plugged with some epoxy of some kind to prevent dirt from gettin in and battery acid getting out.Be careful There is Sulfuric Acid there .DO NOT TOUCH your face or eyes after handling the caps. WASH YOUR HANDS after working in this area.
Ask my wife she see's my ate up pants and shirts from battery acid I contact in my shop.
GOOD LUCK.
ROGER

Great idea!

It appears the fuse would better protect if it was located closer to the battery. Has anyone installed a fuse at the connection to the battery terminal?

We used heavy duty in-line fuses direct to battery in my old TV when I wired in for the 7-way trailer connection. Sal.

Remember that fuses should be located to afford maximum protection to the wiring and components that the wire feeds. When I re-did my battery box to accept the 220 amp/hour Lifeline golf cart batteries, I moved the fuse for the jack right into the battery box and changed the fuse type to a blade type 30 amp maxi fuse in a water-proof casing.

Also added wire loom to the +12VDC wire supplying power to the jack to prevent what happened to you. Just another 'shortcut' that Airstream takes when there are other, safer methods to wire a high-amp component like a jack.

Here is a piece of advice that some may find unhelpful. However I believe it is the best thing you could do right now.

Apparently you are not knowledgeable or experienced with working on 12 volt wiring. There is nothing wrong with this, except that it makes it difficult to utilize long distance troubleshooting help.

You do not need an Airstream Dealer to fix your problem. You simply need someone who is knowledgeable and experienced with Auto or RV wiring to help you.

It looks to me like something is not right with the way the wiring is done in your trailer. There should not be anything wired directly to the battery without a fuse or circuit breaker to protect the wire from the type of damage in your picture.

In my 2010 trailer there is nothing attached directly to the battery posts except the battery cables.

I would strongly suggest that you find someone local to you who can help you figure out what is actually going on.

If you still have your trailer manual, there should be a 12 volt wiring diagram in it. With that and a knowledgeable helper, you should be able to get this fixed in a very short time.

If necessary, use the jack crank that came with your trailer to operate the jack so you can tow it to any nearby RV or trailer repair place.

Apparently these jacks are not all wired alike. Mine has a wire directly on the battery terminal like the O.P., then it passes under the A-frame where it has an in-line fuse, then up past the propane cover (where it pinches and shorts out) to the jack switch. Lousy routing by factory.

I wouldn't move the in-line fuse inside the battery box though, because it could spark when it blows and ignite any hydrogen gas escaping from the batteries.
