Re: Indicator problems.
I think the fuse would knock out other circuits too, there isn't just a fuse for the indicators.
two thoughts - one if the flasher relay. You could try to bypass and see it the indicators light up (they won't plash without it but you can check power/wiring is ok) or it might be dirty contacts in the left hand handlebar switch gear? I had, for a while, only RH indicators because of this and no left turn (had to go 4 times round the block before going home to avoid left turns!! :LOL: not really!!). Unlikely both ways to go at the same time so more likely something else.
I stripped the switch down, cleaned the contacts, reassembled and been a-ok since. If you do this do take care as iirc there is a spring and small ball bearing in there when you strip the switch down.
