Erractic speedo

[nmh]

Hello,

Anyone here experienced an erratic speedo reading. Basically after about 10-15 mins driving from start up my speedo starts swinging everywhere. It will show me my actual speed at intervals so it's not all bad but it also drops to zero. It must be an electrical gremlin that has developed or there could be a simple explanation.

Any thoughts?

No personal experience of that, and no idea to be honest... but...

1) Open the drivers door (keep it open) 2) Press and hold down the trip reset button on the steering shroud (ignition off) 3) Turn the ignition to battery on while still pressing the trip reset button

Shangani posted this in response to a different question, but worth a shot maybe..?

Most likely a loose connection on the wheels speed sensor. Its bolted to the near-side rear hub. I'd start by checking the plug for corrsion and the wires near the plug end for signs of breakage.

Sounds like my rev counter, which doesn't work. It'll work sometimes, then stop. Then swing about randomly as you describe.

Mine did the same,(after a track day) took it into a bloke in Auckland and he rekoned it was the needle comeing loose on the spindle, hence sometimes it works sometimes it doesn't, as it sticks to the spindle again then lets go again (not always in the right place)needs takeing apart and reglueing the needle to the spindle. Mine seems OK now (18 months)did it once again briefly but not for ages.

Had the erratic speedo on mine - wire had broken going into the speed sensor as above

Going to look at this on mine later in the week as I'm sure mine underreads.
Is the same true for the rev counter, does it have a pickup somewhere?
cheers

I had this problem on my s1 and the hole unit had to be replaced. They are about £500. My S2 had the same problem but that was a faulty conection.
