Sorry for not seeing this earlier. We have had very spotty internet on this trip. From what you are saying it sounds like you are talking chassis power. I am not sure what the "board" is that you are referring to is. Most of the chassis power in our 2004 Patriot is centered in the power area in an outside panel below the driver's seat. Is this the "board" you are referring to? And another issue that is unclear is whether you have fuses in this are or circuit breakers. We have circuit breakers on most of this in our rig. Most of the main elements on this power panel are marked so you can trace voltages with a simple voltage meter.
I cannot provide any quick answers since I have fortunately not experienced any problems with our chassis power. But, I would certainly check all items on this panel to see if there is a break in the current.
Not sure they will be the same, but I experienced a similar issue with our 2009 Marquis earlier this year. I found that there are "breakers" located in a cabinet in the rear (engine compartment) on the upper right side in an enclosed cabinet - it had four butterfly type screws holding the cover on. The breakers control several items in the MH, both coach and chassis. It took me forever (4 days of searching) to find my problem, but it turned out to be one of those "breakers" and they are resettable. Good luck
Your run box is no doubt different that mine is .....But...
There are 2 large solenoids in the front run bay under the drivers seat that are activated by the key switch.
One is ignition and one is accessory...
Your ignition solenoid powers up a terminal strip and fuse strips for all items for ignition and running.....check for power on the small terminals with the key on.....it may have failed......or the main self setting 12v breaker that supplies the ignition switch has failed.....it is also in the same front run box
