Can anyone help?????
I have just had my dash re-done with smiths gauges but the guy who is doing it says he cant get the probe on the speedo to give a signal back to the speedo. The probe is fitted to the drive shaft and is supposed to pickup the bolts and send a signal to the speedo but this is not happening......
Help

I had to adjust mine so it was only a few mm away from the bolts on the prop before it picked up a signal.

I have mine about 0.5mm away from the bolts and speedo is still eratic over 65-70mph. Going to bin it out and fit an optical system instead.

Hi,

Mine is mounted on a bracket at 45 degrees to the prop' and I've had to file down the bolts to get the sensor close enough to get a good signal. It's bloody close...about 1mm, gives a steady reading though. If I were doing this again I would go for the magnetic or optical system rather than the proximity system.

Would the sensor respond to magnets?
