Took delivery of my Bran Spanking new.//////////// ooops 20 year Old Fiat Camleot, my first Camper, today. Reading through manuals it mentions a control board where I can view the charge of the Leisure Battery and change from 12 volt to 240 etc Well. errrrmm I can't find it! Did they all have it? was it an optional extra and perhaps I'm searching in vain?
