First posting so be kind! Just acquired our first coachbuilt motorhome. It has a Schaudt EBL266 and the control panel. May be a silly question but what is the switch on the control panel that shows 12v and 0 and a red LED which is permanently lit. It switches a relay over but which has no effect on anything. Also, there is a solar panel fitted but doesnt appear to have anysort of voltage control box, can it cook the leisure battery?, its dead and wont take a charge. Thanks in advance, Shaun.
