Thread: Speedo problem

Hi all Yorkshire newbie.riding into work last week my speedo was showing daft readings like 10mph when I was doing 70 then up an down then nothing. Upon start up it does the electronic test an speedo goes up an down in mph
I'm thinking it's something to do with the sensor. Could any one show me a link to where it is so I can change it myself rather than a costly garage visit .cheers

Sounds like it could be your regulator playing up?

Hi thanks for the reply.dont suppose you've a link to a vid or description how to change it an costs 😁

Run through this check sheet first. You'll need a voltmeter and pay attention when doing the stator checks. Make sure your in AC volts for that test. All the other voltage checks will be in DC volts. There is a fault finding guide for the electrical system. And guide for checking the diodes in the R/R. The R/R suggestion is made because the symptoms your describing are classic charging system failures. Glad you made it home. Typically when the gauges start acting up like this your about 5 miles from total shutdown.

could also be the fuse holder on top of the starter solenoid melted

Thank u for the replies will give it a go when home at the weekend .

The speedo error and failure was symptomatic of my electrical charging system failure some years ago. This took out the stator and the Rec/Reg also. The story of the repair and findings I located here:

Tell tale signs of the impending failure are shown below.
