No rev counter

R1100GS 1999 110,000kms : Strange - no rev counter today ? Any thoughts what to check first ? everything else seems to be working fine . Is this just likely to be a fuse ?

Wow - everyone must be out riding their bikes instead of reading this thread

Checked the wiring diagram and you have 3 wires going to the tacho'

Power
Signal from motronic
Ground (Brown wire)

My money is on a dodgy connector, or earth connection in the loom on the RHS of the beak

will check that first. It's a tricky one to test because I need the tank off to get at the wiring but I need the tank on to run the engine to see if it's working or not

Hmmm.... finally got round to getting under the tank and looking for the problem but I'm damned if I can see anything out of sorts.
I can't actually see an earth on the right side of the beak but I can trace the wiring back from the tacho , down the loom under the tank (more or less) and it all looks OK.
Has anyone ever experienced tacho failure? Could be the tacho itself ?

A mate had a failed Tacho on an 1100

Gecks ..... is there still a hole where the rev counter used to be ?

A hole where the rev counter used to be on an 1100GS is the cup holder on the 1200GS
