1999 Vfr800fi speedo and tach

Ok well i took my bike out and after a 30mi ride i stop to get fuel. And on the way home my speedo and tach all of a sudden stopped working. Everything else on my gauge cluster work "back lights, turn singals, ect. Just my tach and speedo. Anyone have had this problem before?? I'm prepared to do some major tearing part to get to the bottom of this and get it fixed. Thanks for your help!! PS heres another pic i took the other day!!

 

On the older models there is a tach signal wire. Yellow with a green stripe if I recall. Maybe it broke it's connection somewhere.

 

Thanks for the info but I haven't figured it out yet

 

there is a 10a fuse that powers your speedo and the wire goes through a 10 pin grey connecter up by the headlight. this connecter also has gnd and trip wires
