Solar ready

2018 37RB; Does anyone know where the solar panel wires on the roof terminate. Do I need a control panel, or just a solar panel to go solar?

Did you find it?

So, on my new 2018 37GP, it is solar ready. It looks like an MC4 on the roof and the drawing that Thor sent me alone with a chat with the dealer, says it is near my entrance door, on the bathroom wall.

Upon inspection, I don't find anything.. except a COAX cable. I verified it, but turning on all the TV, and unplugging the cable that the coax was jump to.. all my tv lost signal... thus I assume it is from the antennae.

No other cable I can see except 110 power that seems to go to a GFCI plug in the bath.

I thought I would get sneaky and put a wire toner on the MC4 connector on the roof, after I test to make sure that it was not live... then I ran around the wall on the outside with the toner receiver end... nothing. I tried up on the roof near where the diagram has shown and where the dealer suggested it was.. no luck. I started to move around the roof "from inside" and through the whole roof it was on and off, faint tone and non at all.. it was random.. possibly interference with something else.. but the done was there...

I tried on the roof.. no luck either. I only get really high tone, about 2-4 feet in diameter away from where I plug the toner. My worry is that if it was like my radio GPS.. that darn Solar cable is still rolled up and wire tied in a loop.

My Radio kept dropping GPS or not having any.. it was always telling me I was in the side road, and sometime just not work. Upon inspection, the GPS was plugged in behind the radio, but so was the whole GPS puck.. all still rolled up and wired tied under the radio. I unwrapped it and move it toward the window and now it work.

Same was with my AM/FM radio in the garage.. I could not get my NPR, so finally looked behind and it was the same.. the whole 4-6ft of wire was nicely wire tied in spool about 2 inchs in the wall.

Too bad it seems to be this type of workers in the whole industry.. maybe something will happen from the Chinese RV industry.. it might should like it would be cheap, it can't be any worst.. just bad manuals... who cares.. we custom our coaches as soon as we get it here anyway... all the saving could do into customizing or pulling our own solar cables...etc..

Still searching for the factory cables as of now.. hope you find it.
