Hello. I own a 2010 Lexington Forest River class C RV. My Bigfoot Hydraulic leveling system has no power at the panel below my steering wheel unless I turn the key on . with the key off, it doesn’t get any power. My batteries are fully charge so I know it is not the batteries . Does anyone know what could be causing the lack of power unless the key is on. . Any input would be appreciated! Thanks! Lisa
