When you turn the battery disconnect off in the door entrance, it should disconnect all DC power to your coach inside. Your dome lights will not work. Now your frig runs off AC power, so it will continue running if you are hooked up to shore power.

Art,
I have a 2001 Dynasty and hopefully I can provide a possible solution to your question.

I would suspect that you have one of the two 12 volt solenoid relays that has the internal contacts stuck in the ON position, even though the 12 volt control voltage has been been removed as a result of the rocker switch being turned to the OFF position as you referenced.

On my coach, when you turn the rocker switch to OFF, which is located by the entry steps, it should cut off all 12 volt power to components on my coach, except the refrigerator. This Battery Cut-Off rocker switch controls two different 12 volt relays (Cole Hersee part no. 24059, 12v, 85A, continuous duty relay). These relays are located in the front section of the rear run bay (electrical compartment) located behind the battery compartment. I as well had one of these hang up or stick on me which resulted in a problem similar to what ypu are experiencing. I diagnosed it by going back into the electrical compartment and jumpered 12 v control voltage directly to the solenoid and it started working. As a result I replaced both of these Cole Hersee solenoid relays, which can be purchase at most all automotive parts stores for around $20-25.

As information, my Norcold refrigerator 12v power supply is not controlled by the Battery Cut-Off switch near the entry steps. The refrigerator power is supplied from a 12 v circuit breaker located in rear portion of the same rear run bay (electric compartment).

Hope this helps and happy RV'g.

Jack

Thanks' guys that confirms what I thought. I have a Foretravel with Aqua Hot and when you shut off the batts Aqua Hot-Refer and a couple of other things are not affected. I wonder why they use 2 solenoids? The owner of this coach just bought the coach so he's not sure what it;s supposed to do. Like I said in the Post I can hear a click in battery compartment and a couple of things shut off but all lights stay on. My coach came with a complete set of AC-DC-Air and water schematics, that makes trouble shooting much easier. If Jack or any one has a picture or a schematics of that compartment that would be vary helpful, Thinks; Art

Art,
As you requested, I have attached a few photos that I placed in a PDF document that helps illustrate the layout of the rear run bay (electrical compartment) on my 2001 Monaco Dynasty. These photos illustrate the location and appearance of the 2 each, 12 v Cole-Hersee Solenoid Relays controlled by the Battery Cut-Off Switch. These photos also illustrate the location of the Circuit Breaker that provides 12 v power to operate my Norcold Refrigerator which is NOT controlled by the Battery Cut-Off switch near the entry steps.

As a follow up note, the sound of one of the relays snapping in can be confusing as you might think that all is well, but in reality the sound made by the one relay will disguise the fact that the other (2nd) relay is not actually pulling in.

Hope this helps and happy RV'g

Jack
