Anyone fitted an intelligent speed sensor ?
Discussion
Hi guys, as the title says, i was wondering if anyone has fitted the Steve Heath intelligent speed sensor instead of the old speed transducer at the diff.
Cerb has been used very little for the last 6 months but had her out on sunday for a wee blast and speedo chucked it. Dancing about a bit and seemed to respond to the old "tap the gauge", but alas i fear the worst.
How temperamental are the old transducers and is there a way to check them before replacing as it appears to be a bit of a b
h to replace.
I seem to recall reading about the rev counters dancing about and this was a sign of a cracked Big fuse, could this be the same ?
Any suggestions greatly appreciated. Ta.

The prototype was developed on my Cerbera after I had similar symptoms and I had got fed up with replacing the sensor several times. Biggest problem is the 10 thou gap that it needs to sense the trigger wheel which means it can easily be damaged by grit or even colliding with the trigger wheel itself. The problem is that it really needs an oscilloscope to see the wave forms and also the trigger wheel needs to moving. For most people this means there is no real way of testing the original sensor or the speedo. This is why I built in diagnostics into the interface unit so you can check the speedo independantly of the sensor. The sensor has its own diagnostic LED which addresses the "how to setup and test the sensor" issue. And yse your symptoms sound the same as mine. Eventually my sensor died completely.
Changing the sensor isn't that difficult as the setup comes with a new mounting plate. Access to the speedo unit is easy as all it takes is for two wing nuts to be undone and the top cover comes off and the speedo is just sitting there.
They tend not to be so open to the big fuse problem in the same way that the rev counter is. If the big fuse is cracked I would expect the rev counter to move around and otrher electrical issues such as a low battery to happen as well.

Loads of space. Unplug speedo connector, plug in the interface/test box. The box has a simple switch that turns it into test or run modes. I keep the box tucked up in the steering cowling. Easy to get at should I need to use/demo it.
The new sensor is also intelligent enough to now which way round the leads go so they can be wired in either way round. It makes no difference.
