Fuse thing in the Speedo

[Bluestoesonnose]

Ok, I'm stumped, what the heck does the fuse thing do in the back of the Speedo, it's got wires on it and is connected to the loom but I can't figure out it's function.

It's a 2002 DT125R if that helps?

@Bluestoesonnose it's a reed switch, that limits your top speed

@finnerz89 Ah, cheers
