I have a 2010 winnebago journey replaced dead batteries back in summer of 2019. All worked well. Have only started rv 1 time, no problems. Attempted to start the other day, no power. Have tried and recharged batteries. All batteries both chassis and house show 12.87 volts. no power at the disconnect inside door at switch panel. Nothing happens when switching house or chassis disconnect switches no clicks or lights. No power to ignition switch. Wont start. Haven't tried cleaning connections...
