I do not believe I have ever seen or heard an electric horn on a Monaco coach. Only the roof mounted air horns. 
     To Dr4Films’ point, I have installed a train horn in my last two coaches for the “stupid drivers”. It may not be legal however the level of satisfaction when I use it is well worth the risk.  
safe travels. 

Have you checked or bypassed the "salesman disconnect switch"?

Try F-62 or anything marked aux. in the front run bay. You might also pull the little glove box out on the passenger side and check to see if there is a inline fuse going to the switch. Sometimes previous ownership leaves unknown challenges. May not be your case, just saying.   Good Luck

I have the same light on my dash and it is the brake indicator for my toad. Comes on when the brakes are applied on the tow vehicle, which has an Air Force One system.   

Look for " parking lights"  thats how mine are labeled on my 08 camelot. And it should be in the fuse bay on the drivers side front bay. Could be a relay as some coaches these lights will also blink with the flashers on .  Good luck

Doug   This schematic is labeled 09 however is exactly how my 08 built in 07 Camelot 42DSQ. I think they used one wiring harness for all coaches.

Brett       I would reboot the intellitec system and if that does not work call the intellitec technical help line. I think the guy's name is Chris. He is very helpful. Try 386-738-8135.  Good luck

Today I found two very loose connections on the buss bar behind the intellitec panel. Tightened them up and my issue has been solved.

Thanks to all for your insights and especially Frank McElroy for the files. This web sight and ya'll are awsome

  Larry   Are you referring to this black box ?

Yes, I replaced it and tested  the new one, Then bypassed it anyway with a jumper just to be sure. Because it always reset itself is why I am thinking the Magnum or a relay?  Thanks 

Good ideas Frank,  I have checked and tightened and exercised every connection and connector that I can find including going deep into the panels. I even found the master ground connections on the main frame and crawled in and removed cleaned and reconnected. When I lose the 12 vdc house, I lose everything (slides, intellitec system lights and fans, sanicon, outside radio. the chassis battery side is fine and I have 120ac when this happens. I am thinking I might have a issue with the magnum inverter shutting down the 12 volt system even though my batteries are full charge. I have done a hard and soft reset on the magnum.  Or there is a 5 dollar relay somewhere acting up that I cannot find? Issue continues.  Thanks Doug

Cubflyer   To better clarify.  I have a total power outage on the house 12 volt system when my issue occurs. If I use one of the bigger slides or the sanicon or all three fans on high, the power shuts off completely for a couple minutes and then comes back on and everything works. When this happens the magnum remote control reads 13.4 or higher. I do not lose power to the magnum remote control display just everything on the House 12 volt. ??   Intellitec tech walked me through a couple "tests" and ruled out the Intellitec EMS board.  

Thanks for the reply. We put a meter on the batteries while running and replicating the issue. There was no significant unusual or heavy draw down on the batteries during the test. Thanks

We are plugged in to 50 amps. 

My 2008 camelot 42DSQ drops the house 12 volt for a short time when I use a heavier 12 volt load. Power restores in a minute or so. All chassis and 120 AC works fine. I have verified the battery disconnect solenoid is working ( even bypassed it, still same issue) New batteries,with new lugs on cables and cleaned the master grounds to the coach chassis frame rail behind the battery compartment. tested the draw down while running rear slide. RV Electrical expert that spent 2 hours checking all systems while I replicated the issue is stumped.  Any ideas welcome.  Thanks 

I have a 2008 camelot 42 DSQ. My issue is when I use a heavy load on the house 12 volt system ( slides, sanicon all 3 fantastic fans on high) the entire house power drops out for 1-3 minutes and then restores. I do not loose chasis 12 volt or any of the 120AC, only house 12 volt DC. I have checked the battery disconnect solenoid and it is OK. Intellitec tech told me I have a loose ground. I did finally find and clean the main grounds to the chassis ( located behind the battery compartment) still have the same issue. Batteries are new. Any ideas or suggestions welcome.  Thanks Doug
