Just noticed on today's ride: Speedometer dial doesn't move, and odometer not 'counting'. Just got it out of the shop for brake master cyclinder replacement.

I looked up the K1100LT Service manual for Speedometer drive: where is it located? by the rear paralever unit?
Embarassed

Searched through K11OG forum... no luck.

Instrument cluster otherwise seems fine, I was wondering if an electrical rather than mechanical root cause. Weather was in the 40's but warmed up to the 60s, so I'm nnot thinking a stuck dial...which still doesn't explain the odometer counter not registering.

The sensor is on the rear drive, follow the only wire going to the rear drive and you'll find it.

Number 6,

Thanks for the prompt reply. I'll start off with the Speedo drive, then check connectivity back to the instrument cluster.

Since it's both the Speedo and the Odometer, i suspect the Speedo drive rather than electrical or mechanical (plastic gears) in the intrument panel.

Feedback?

Greetings Seavoyage,
The speedo is quite involved technically.
In the final drive is a black / silver chequered ring. The bit on the top of the FD is an optical sensor. The pulses travel via the Brown + yellow wires to the speedo AND the indicator relay.
Do your indicators auto cancel after 300 Metres? this could help diagnosis.
Most common failure is rotten connections under the tank. Followed by the fat plug on the back of the Cluster.
A mate has had the ring in the FD fall off which would cause your symptoms too.

Tim,

Thanks for the response. No, the turn indicators do not autocancel. As I previously mentioned, the speedometer dial does not move, and the odometer counter does not change.

What is diagnosis based on the self canceling turn indicators?

Will do a trace from speedometer drive (remove from rear drive housing to inspect for black/silver ring, trace the brown/yellow wires, to junction under right side/panel next to battery, up to instrument cluster. And run electric cleaner on the junctions.

Scott,

Brilliant!

Found the wiring schematic: English B/W http://skene.org/k1100/wiring/wiring_diagram.gif

But couldn't find the German Color schematic you posted : http://www.cafezurburg.de/petergrans/pdf/K11002.2Fahrwerkschaltplanweb.pdf

Any other links for a colored schematic?

Someone may have some pictures of the optical sensor on the final drive...

As soon as I get this Speedometer/Odometer malfunction sorted... I should probaly try to calibrate the Speedometer ...

Any experience with flyingbrick.de software program?
Confused

Traced the yellow/brown leads from sensor to junction next to cooland overflow tank to instrument cluster. Cleaned junctions. Still no change.

Next step: Per Tim's recommendation: checking resistance and electric potential (V). Stand by...

Do i get the impression that you've decided to sell the fault?
A pity, I was looking forward to hearing what the cure eventually was.

Traced Brown and Yellow and cleaned all junctions. Eliminated speedometer sensor as fault.

Pending part from a parted out K100RS at Werkstatt.

Now that we've got it sorted, a young Airman at Travis AFB is working on the project.
