Thank you this is helpful.
What I did is connect 1.5v Duracell battery to a cable to MC4 connector on roof and measure voltage with Fluke multi meter.
Red + White measured as -1.6v, I think somehow it is b/c I switched pos/neg but that's good enough to know Red/White IS connected to roof solar receptacle.
When I measure White + Black, key is in and turned dash on but engine not started, house battery is also on, LED light in RV lighted. Voltage between White + Black is open, between White + Black with red strip is also open so they are not connected to any batteries, I believe someone in Jayco may forgot to connect them to battery.
