Trailer audio/video wiring diagram for 3850RL
We have a 2016 Cardinal 3850RL with a Furrion DV1200 audio system. The system seems to work fine except when in AUX and we turn off the unit -there is a loud pop sound. It also happens when the TV changes picture resolution. Called Furrion and they sent me another DV1200. I replaced it - same problem. Turning off the unit in other modes AM/FM, DVD, etc does not give the pop noise.
While I had the unit dismounted, I verified the wiring. There are two wiring plugs one for power and A/B speakers. The other is only for C speaker (outside). Everything on the main plug looked okay, but found the subwoofer connected to the "C" right output channel rather than the DV1200 subwoofer output. This makes me think that there is only one pair of wires to the "C" speaker (there should be two pair). They have also run an HDMI cable, along with an RCA cable for video/audio, from the DV1200 to the main TV. Why both?
There is also a cable plugged into the DV1200 at the only remaining RCA video output. No clue where it goes. Where ever it goes its just video with no audio connections.
Consequently, I was wondering if anyone on the forum has the 3850RL (I'm sure its the same for all Cardinals) wiring diagram for audio/video? I'd sure like to see a Forest River wiring diagram to see what wires go to the C speakers. It would be nice to get the wiring correct before I continue with a resolve of the pop noise at shutdown.
