1986 FZ600 - No Tachometer ?

[CaribooFZ]

Hope this is the right place to post this... (New to the forums)

I have a 1986 FZ600 that I have been restoring over the winter and I'm almost ready to put it back on the road. (Need a few small parts... and paint...)

However, I am up against a stumble... The Tachometer does not move. Bike starts and runs fine, the tach lights up, but needle does not move at all? I have traced the wiring as best I could, checked fuses, etc... still no luck...

Any suggestions on what to look for?

Thanks in advance... Looking forward to being part of the group...
