NEED- 2012 Tiffin Phaeton-Freightliner Ign. electrical wiring drawing

2012 Tiffin Phaeton, no start from key, starts fine with aux sw. , so here is my dilemma.

My starting batteries are 3 months old, all connections are clean and tight. Voltage is good on batteries.
Will do nothing when key switch is turned on, no dash, not start no nothing.

When I use aux bypass that is suppose to only close the Chassis sol. back in rear Passenger side basement compartment, bring on house batteries in parallel with starting batteries, all works.

Now, this tells me that when aux switch is used, it not only brings on the 12VDC from chassis batteries, BUT IT MUST ALSO BYPASS THE KEY SWITCH CIRCUITRY, AND THIS WOULD SEEM TO SAY, THAT CIRCUITRY IS THE PROBLEM.

SHAME ON FREIGHTLINER AND ALL OTHERS, TIFFIN, CUMMINS, FOR NOT PROVIDING 100% ACCURATE ELECTRICAL DRAWINGS TO VEHICLE OWNER
SO WE CAN TROUBLESHOOT THESE TYPES OF PROBLEMS.

YES , I HAVE CALLED FREIGHTLINER, NO I HAVE NOT YT OBTAINED A DRAWING (S) THAT CORRECTLY SHOW THIS CIRCUITRY, I WAS AN INDUSTRIAL MASTER ELECTRICIAN, AND LATER AN ELECTRICAL ENGINEER
FOR 45 YEARS, SO I AM NOT SPEAKING FROM A PLACE OF IGNORANCE.

If anyone has a complete electrical wiring diagram, or schematic that accurately indicates the Start batteries to the ign. key sw. and starter solenoid, and also the circuitry from the Aux switch to the Start sol. for a 2012 Tiffin phaeton/Freightliner I would be so appreciative.

Sounds like your chassis battery disconnect solenoid is open. Did you hit the disconnect switch by accident??

Hey, thank you for your reply. I found the problem, no thanks to having a decent Tiffin:Freightliner electrical drawing. As it turns out, this MH has a drivers sife front basement compartment, with a small enclodure called the PDM, power distribution module.
This module is really a box with 12VDC relays, fuses and circuit breakers that also control relay for ignition system. The ign relay contact pins had become wet and just slightly corroded. Cleaned with White Vinegar and q tip, took care of issue. Covered PDM To prevent a reoccurrence. Thanks to all who offer help.
