Two 12 v light fixtures out, where to start?
« on: May 07, 2018, 03:33:01 PM »
First post. I've been lurking, reading & learning. Lots of info to digest, almost feel like I'm in school again (after 30 yrs).
We bought a 2012 tt in Dec '17. It's a Keystone Bullet (281BHS). We're generally pleased and finally got the tanks to read empty thanks to some tips on the forum, thank you.
New issue. Two 12 v light fixtures stopped working within minutes of each other. They are both located in the slide-out, one above the sink and the other above the couch. I turned the one above the sink on and it flashed on then off. I was doubtful both bulbs would die simultaneously. I removed the lens cap & removed a bulb. I turned on the fixture above the couch & same thing, it flashed on then off. I checked the lights above the TV & they work. So I moved those two bulbs to fixture above sink, no work. I moved the sink bulbs to the fixture above TV & now they work.
Since both fixtures (4 bulbs) stopped working at basically the same time (but bulbs work) and they are both in the slide-out, I'm thinking somehow with the repeated in/out movement has damaged the wiring. What else could be damaged (water line....). But that's for another post.
Finally my question. How do I gain access to the wires for those fixtures?
Thanks in advance, Bill

Well I can think of possible issues. like fuses that failed (Not blown but failed, same effect differenc cause) you might check the fuses

Under the slide (usually) is a junction box or two. Romex in and flexible cable out or the other way around (one of each) and this has been teh problem on some RV's.. Odds of a problem between that box and the light are . .. Well not zero but close to it.
Nothing adds excitement like something that is none of your business

Thanks DET or DTW. That's what the wife thought. I pulled a fuse and a red "idiot" light came on. So I'm assuming the rest of the fuses are working.
I really do NOT want to take this to a shop. Can't imagine how they'd investigate this foreverrrrr ($$$$$).

I had a similar problem recently.  The red idiot lights are SUPPOSED to mean the fuse is blown.  I had one that "partially blew".  It passed enough current to keep the idiot light off, but not enough to light a bulb.

Bottom line:  You are not alone on this!
