(wont start or turn over though) If u turn the headlight switch on and off everything goes off /back to normal also the brake control flashes and goes off when the headlite switch is pulled on/off as the other stuffany and all ideas and questions welcome

I'd be looking for a bad ground connection somewhere with all those odd symptoms.

Some of your listed items are on the coach battery system. Have you cycled the chassis battetry disconnect?Have you had any battery(ies) worked on?Check around battery(ies) for a dropped cable.

Think you have a control failure. A short and you would not have anything electrical working. Try these links. There were several recall on this. Its a old system and no repair that I have found, just remove and go without or put in another system. Its was a monitoring system that did not last long. Too long ago to remember all the issues. Seems like you could turn it all off and take the power off it. The first link might have that info.Eplex#2

System could be back feeding to the dash via the charge relay system.
Possible from bad ground. Check connections in battery compartment.

I already did that but going saturday to recheck things like that
the more i think about it it really has to be a grounding issue because of things like pulling the headlite switch on/off shuts off the phantom power feeding the dash etc
what you think ??
appreciate your help here in this matter

another dumb question I open the electrical compartment and see two black solenoids one I assume is for boost and one is for??
I check with test lite and power to both side of both solenoids with chassis battery's on or off

One should be the COACH battery disconnect. Test the solenoids with Coach disconnect OFF and NO 120 Power to the RV. Doug
