Hello everyone, The Tourneo Custom and the Transit Custom in the car version basically have two batteries. I would like to know how they are connected. Simply parallel or is there a separation relay that prevents both batteries from being empty when you hear a lot (& loud) radio? Furthermore the question: Does anyone already have a schematic of one of these vehicles? I have created a new topic, because the electrics is just a separate topic. (e.g. the ECO button or the question of whether you can configure this button only for switching on and off the start/stop automatic – without the speed limit to 110km/h – via OBD interface) Feel Ford running (or hopefully driving) saluted Lothisch
