Good morning, I have an understanding question: We bought a caravan Hymer Moving 540 B Autark from 2002. We still have to pick up the car. I have a question for this: 1. Are the consumers switched to 12V? 2. is the battery charged during the journey? Did my old WW switch this so that the cooling is switched over a line from the car and the battery is switched over another line. And all this so that it is only charged at over 13,4 V. (d) en background that does not go too much A over the plug. Hope on energetic posts. Greetings Dexal01
