Can any funster give me an idea where to find the leisure battery charging fuse on my 2004 ducato Rollerteam 15p.Bateries are charging o/k on mains and solar but not when we are driving.This has led to the demise of both.I have checked the fuses just above the batteries and they are fine.Please help,We are travelling at the moment so internet is only possible now and again.Thank's in advance Martin&Sue
