I have several electrical problems that my dealer can't resolve. Does anyone have electrical diagrams for a 2017 or 2018 Sprinter Citation or Siesta? The starter battery is dead in about a week. The solar panel that the factory installed does not work, no voltage from the house batteries to the controller to make in work. My tvs will not get HDMI input from the Radio/DVD player. The WiFi box was put in a cabinet without a 120V receptacle to make it work??? Besides electrical stuff, my gray tank leaks and you can't get to it without removal of Black tank. The reason I can't get service is my local dealer ordered this for me, but he is not a Thor dealer. He went thru a friend a good distance from here and Thor will not supply him electrical diagrams for troubleshooting this new model. Any electrical diagrams out there?
