Recently purchased this motorhome and the fridge does not run of 12V with engine running and the leisure battery does not charge from the alternator. I realise it may be a problem with the D+ feed but can't find the in line fuse. Its the model with the leisure battery located under the chassis by left door, starter battery under cab floor, habitation 12v fuse box behind drivers seat and charger under drivers seat. If anyone can point me in the right direction it would be really appreciated!!
