Hi, I currently have the same issue with the tachometer on my 1989 grey cab 3CX. As suggested the 'W' connection/post on the alternator is where the tachometer wire should be connected and you could test the output from this with a voltmeter just to make sure there is an output. If not, I have been ...

Hi
Thanks very much for your answer to my question.

Is the only solution to weld some pads on the inside of the leg housing or can anyone suggest an alternative rem...

Hi thanks for the replies! Ian, I have the same instrument panel as the top one shown in your pictures. I have had it out and there is no sign of anywhere to attach a mechanical drive cable so I’m sure it is electronic. The temp gauge is not working either so it could be linked? I had no lights but ...

I have a 1990 3CX and the tachometer is not working.

Is the tacho on this model controlled electrinically by a sensor on the alternator?

Also, could anyone suggest the best method of fault finding please?

Thanks in advance.
