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.
