Looks like they have a cap on them that you have to open to get to the fuse.
Take a few pictures and post em here. Curious to see how it looks inside there.
Actually now I can't unscrew the front cover the get to the battery case where the fuses are, the screw is too tight and won't budge - (imagine being in a blown fuse breakdown, needing to change a fuse but unable to open it up!)
I'll take it to the dealer's workshop and ask for help, they'll have more powerful tools. Don't like asking them for help like this - when I rang to ask what type of spare fuses, they just said they weren't certain, but 'probably' glass cylinder type although 'not sure' what length and 'probably' a spare already in there, but that I should open it up and look. As I can't even achieve that now, I'll have to return to them for assistance.
Jeeves you've been far more helpful than the dealer's workshop, so thanks again. It's just unsettling in the interim, in case a fuse blew and I was stranded and unable to deal with it, but with any luck that won't occur and hopefully this back-up plan will eventually be sorted.
Cheers.
