IGN electric problem

[dkh]

Picked up my 2016 Tiffin Allegro Bus 37AP from storage today and my
electric window, mirrors, Cameras,slides, mobil eye, a/c and step all have lost power. I checked all the fuses, breakers that I could find and nothing burnt or popped. Any advice would be appreciated. Thanks

Need more info. Does it start. Dead battery?

[dkh]

Yes the motorhome starts and runs. The step will come in if I shut the house battery off with the door shut and turn it back on but doesn’t come in when the ignition is turned on. Everything else I mention does not work

Is there a 12V disconnect (aka "salesman") switch?

[dkh]

Yes there is

On my Tiffin Open Road Gas the fuse circuit panel has one set of fuses that is powered with a relay when the ignition is on. I'm guessing your bus has a similar set up and for some reason that relay isn't working, either the relay is bad or the signal that activates that relay is not getting the ignition signal.

If you call Tiffin they should be able to assist you. They sent me a schematic and drawing for my panel. If they could send you the same drawings for your bus it would be very helpful in figuring out what is going on, or what you are experiencing may be something that happens and they can tell you how to resolve it.

Good luck.

😁 I removed the four ft relays and found the bad one and all is good.
Thank you all for your help.
