12v power shut off

I pulled into an RV park late tonight and during leveling the 12v power shut down. Completely off. All 12v things are dead. I plugged in to 30 amps and TV's and micro works. That's all though. This is a new to me 2007 Monaco Camelot 40 pdq. Any one know where the main 12v fuse is located? I looked in the battery compartment and saw no main fuse. Any ideas where to start looking for a breaker or a fuse?

    Sounds like Monaco uses the same 12v type solenoid switch that Travel Supreme uses. I just replaced our solenoid this morning original since 2003. We had the same problem all 12v was off in the MH. We have a switch at our entry door that turns the 12v on or off, and after testing the switch was good. So I ordered a spare Cole Hersee - 12V Insulated Continuous Duty SPST Solenoid at http://www.partdeal.com/cole-hersee-12v-insulated-continuous-duty-spst-solenoid-boxed-pkg-24059-bx.html to carry in my MH.

    It was easy to change and in the future if it goes bad I will have a spare.
  • I found it this morning, a 12v breaker had tripped. I looked right at it last night with a flashlight but didn't see it. It was located in the battery / solar connection bay where the manual battery cut off switches are. Thanks for the help.

  • Have you checked the breaker box for a breaker that flipped?
  • Still,

    I don't know Monaco from Macau - But I work on different things all the time.

    Look in the battery compartment. Do any of the cables go to a large block you do not recognize? That may well be a system fuse. It need not have actually blown, I have known of several that just got loose and quit. Cleaning and tightening was all that was required. This is usually close to the batteries.

    Next pull and shake every cable and make sure none are loose.

    Find the 12V distribution panel.
    Look for the large cable that feeds it and make sure it is solid.

    Most all the new converters have fuses. If you were doing something like running slides when things went bad, the fuses in that could have gone.

    Well, past this we need a meter or a good test test light.
    If you don't have any meter, stop by Hazard Fright and get the cheapest. That will still beat nothing.

  • Perhaps your converter has died. Those symptoms fit with my experience with converter issues.
  • I had the same issue with my TT, more than once. Suddenly late one night, darkness, no 12V, everything dead.

    Somewhere in the mix is a 12V feed fuse.

    Mine was a TT, different form a MH, but the same concept applies - find the main 12V fuse.

    Mine came from the house batteries, not too far from my hitch, ridiculously hidden behind my hitch up tight close to the floor.

    I suggest you follow your house batteries carefully and find the fuse and check it out.

    Mine was caused by a corroded fuse and holder.
