i'm trying to use the 7 pin trailer connection on my 2017 170x sprinter Winnebago era 4x4.
i have built a wiring rig that let's me plug, just to light up a license plate frame that will mount to a cargo box.
my problem is that i'm not getting voltage to the running lights wire. i get voltage from the constant 12 v circuit. i have also visually confirmed that the fuse is in tact.
this video: https://www.youtube.com/watch?v=YDh8BGD-TRQ shows me testing these circuits with my voltmeter. you can see that the running lights (and the left blinker) just do this weird floating 1.5 volt output thing.
what do i next debug? why would the constant 12 v circuit be fine, but the running lights and indicators only put out a fluctuating low voltage.
thx!
