Torago electrics fixed
I finally found where my darling wife had hidden the drivers manual, besides the two fuse boxes under the bonet there are two more in the cab under the dash
The fuse I needed to replace was on the pasanger side up against the firewall behind a massive collection of wires. To see it you have to remove the glovebox and to get at it you have to remove part of the trim and stand on your head on the floor
