2009 HR Endeavor 41 SKQ we lost most but not all 12 v function on our drive out of North Yellowstone this morning. Intelitech is dead, pump, 12v feeds to the roof A/C's, driver passenger power seats, etc. The Magnum inverter charger is on and says it's charging. Any idea's?

2 x on the bypass, they will give you trouble sooner or later.

Bypassed mine..that thing would pop if you bounced against it while exiting the coach.

Glad you found it. After hitting ours a couple of times and finding the AC's do not run with it off I bypassed the solenoid it controls. We too have dogs and it worried me that the AC's could get turned off while we were out for a while. It is a common procedure and very simple to do. I own a 2008 SKQ.

Yep, we tried that and it worked. The dogs must have hit it with their tails. Thanks! Sometimes it's the simplest little things...

Yes, call Monaco 877-466-6226 and have the last six of your vin handy. I'd check for 12V on the large red cables in the front run box under your feet... outside. If you have 12V then which boards are not lit up before calling.
Probably in the bathroom there is a 12V fuse panel... 12V there? It gets it's power from the back run box on the right in the engine bay.

And the simplest solution... turn on the disconnect switch by the door BUT the seats are not on that part of the 12V system usually.
