12 V aux jacks not fused?

[gaylec]

This is Gayle's husband. Jud. There is what looks like a headphone jack near each of the bed drop-downs. Nothing in the documentation says what they are for, so I did a little investigating. They are 2 pole connectors, wired with a black and a white wire and hold a steady 13.3 V DC level. Strange way to do auxiliary power jacks in my opinion, but maybe this is the way in the RV world (a headphone jack, really?). So, I wanted to know which fuse on the converter they went through and kept pulling fuses until I found it. Finally, with all the fuses out and the power still live I pulled the charge line fuse and that did it. What that tells me is that there are two power jacks, using headphone jack connectors that are hard wired directly to the converter output. That is crazy in my opinion. Anyone have any insight to this?

We also have those headphone jacks you are talking about. They are pretty standard near most beds in a camper from my experience. I have a fan with a light on it that plugs into them and then they clip onto the pole above our bed. I think that might be what your talking about.

Very common to have stand alone jacks or jacks incorporated into a light fixture in popup trailers or hybrid trailers. Not sure if they are common on other types of trailers. My 17Z did not come with them, so I added them to my camper. They are used to run 12 volt lights or fan/light combos.

Jud, what do you have for a HTT? Did you purchase it new or used? From what I can tell some models, some years they came with the HTT as an option.

My 2012 X23B, did not come with them nor where they an option. I installed them myself, and it was a little bit of work to route the forward bunk wires to the converter/fuse box.

I would suspect, if you have a used HTT the previous owner may have directly wired them to the battery. But that is just a guess. Another thought, they kept blowing fuses as the plug was pulled out of the outlet. I had this issue, until I determined the reason and then fixed it. Because of the above stated issue they may have rewired it to bypass any fuses behind the fuse panel. But again just a guess. If you have that issue let me know.

You should be able to track the wires, the front bunk end wires should be the easiest to track. Most people route the wires through a small wireway, down the wall (street-side front corner). From there just crawl around and determine where the wire goes. Once you determine where the wires go you can also determine if they are fused or not. If they are not fused, you could install in inline fuse holder with a 15 amp fuse.

My 2013 X19H has those inputs as well. What are they for? What accessories can you plug into them? They don't go to the stereo do they? (Logical thinking would say that headphone jacks would be wired to the stereo and/or TV for listening to music at night, but I'm not logical). Any help would be appreciated. Thanks, and Happy Camping.

This is kind of what I had in my pop-up.

It's a reading light with a fan combination. Snaps onto the tenting rafter pole.

Mine is a light/fan combo that mounts to the bunk end roof support bar. They do make ones that are only a light or a fan unit. The plug looks just like a headphone jack.
