Having issues with the USB sockets in Scamper, none were working. Failed to realise that the Ducato USB sockets, which were working, were not controlled by the same fuses as the Scamper USB sockets which were not working. Overnight stopover in a small village of Luintra in a sports facility car park near to Ourense. Ourense has a main Fiat dealership. Next morning called into the dealer who were very friendly, had a look at the Fiat fuses and pronounced they them all working OK. Suggestion was that Westfalia have their own fuses controlling USB sockets. Hmmmm Looked at the Westfalia manual and sure enough there are a bank of Westfalia fuses under the passenger seat. Replaced a 5amp fuse controlling the USB's and all fixed
