Welcome on board Richard.
Glad you got it up and running. Fuse number 6 at fault by any chance?
Just keep an eye on things for a while. Although fuses can blow inexplicably and for no reason at all, they do generally blow because of an electrical fault causing an open/short circuit somewhere. At least for now carry a spare 10A fuse in case it goes again, and if it does, you'll have to delve a bit deeper into the problem that's causing it to blow. All being well, it'll hopefully just be one of those freak occurrences.
