I have a 2016 Excursion, 36K. The dash radio and the radio in the outside entertainment center will not power up.
These radios have 2 power lines, one is red and is 'switched power', the other is yellow and is on constantly. NOTE the red and yellow leads are the leads in the wiring harness for the radios, the color coding for the 'coach side of the wiring harness is not color coded the same.
The constant power is what keeps your stations, settings, etc. in the radio when it is turned off. I have located the fuse for the red lead and all is well.
My issue is with the yellow lead, the constant 12v, it is dead on both radios and I cannot find a fuse. I have copies of the wiring diagrams for the coach and I cannot find that circuit anywhere.
Any and all help is appreciated! TIA
