Dodgy Regulator?  It's the half moon plastic unit in the back of the alternator.

cable possibly shorting as it runs round the front of the cylinder head?

Hi,
    Which cable have you disconnected on the alternator? If the Brown/Yellow wire was shorting it would keep the charge light on but not blow any fuses.If it was the White/Silver wire(rev counter pulse signal) I think it's unlikely to blow a fuse, more likely to just stop the rev counter working but worth checking anyway as I don't know if the internal circuits in the rev counter would allow a short circuit, possibly a fault in the rev counter itself.
 Keep us posted how you get on.
