Last evening, I noted that my back up lights were on while parked in the driveway ... no shore power. I contacted JC customer service and was walked through three steps to troubleshoot my situation. It turned out to be moisture in the 7-way extension (to accommodate hitch). Thank you to JC. Everything is air drying now. As soon as I unplugged the lights went out.
You must keep your powder and wiring dry... WD40 will dissipate the moisture... but it will also attract dirt..
So, I use 'electric contact cleaner'... then apply some Dielectric Grease... no mo prob.
Oh.. hand the end of the cable (umbilical)/7way wiring, under the Propane cover.. it is usually dry there..
Always leave the 'end' of the connector hanging toward the ground.. but do NOT get it in the dirt !! or mud!!! If you do, clean as above and re-protect.
