Thanks for all the replies everyone.
I had an opportunity to go work on the RV today and I took the salesman switch that I originally removed and replaced it. As I wired it up, I heard a click that I believe is above the doorway. After completing the re installation of the switch, I turned it off and on several times and heard the click every single time. I believe it is coming from the Heart Interface which has the inverter on/off switch along with a series of leds showing current levels for the different electrical systems.
All that said, everything is now working like it should! Every time the salesman switch was turned on, I heard the click but all the coach lights came on. When turned off I again heard the noise above me, but none of the lights came on. I wish my wife would have been there as I could have had her put her hand on it to see if that is what is making the noise.
Jeff, sorry I did not get a chance to open the engine bay and take a picture. Another member e-mailed me and told me which solenoid that the switch controls. Here is the picture he sent me of his (as far as I can tell, mine looks exactly like his). He also put an arrow on the solenoid to check out.

K7JV, To answer your first question I have been in the martial arts forever, thus the screen name. Do you think you can clean the contacts of the solenoid in the above picture? That is the one controlled by the salesman switch at the door. Our battery cut off switches are located at the top left of this electrical box in the engine bay. As I said in my original post, I checked them and they are working fine.
Nothermark, like I originally said I attached them because nothing worked (coach or chassis) and every time I turned that switch on the battery level monitor would show some current then quickly die. I have since checked the switch using my car battery and a 12 volt test light. It works perfectly and I reinstalled it this afternoon. That is when I starting hearing clicks that I believe are coming from above the door. I am not an expert but don't think there is any way you could hurt anything as all I did was bypass the switch. The switch simply lets current run through it in the on position. Hooking the wires up is exactly what happens when you turn the switch on (as long as the switch works). Please correct me if I am wrong, but that is my understanding of a two wire DC switch. Other members have told me that the salesman switch controls a much larger solenoid in the electrical box in the engine bay. That is where I think my problems are coming from (fingers crossed).
JC1, thanks as that is the same info I received from another member earlier today. He also sent me that picture above and showed me which one to check.
Again, great group on here and I will keep you posted on my progress!
