Something crude like a multi-meter with a Hz setting will also do, or a scope. OR even a volt meter on the AC setting.

right put meter on it this morning on settings acv 200 its the lowest setting on there and all i get with driver circuit on it i get 28.8 and nothing else when i rev it it stays as it is
then i did m/s side of it and got no reading so i switched it to dcv and got -0.02 when reved it altered to 0.00 and that was it
any clues whats wrong with it the m/s is running fine i just want the tacho back other wise turbo timer etc dont work
cheers

If you get an LED test light at low rpms you should be able to see the led flickering if you probe the transistor base and then the output.Megamanual shows how to make one from a pen case, led,needle,wire and a resistor.That is if you cant get hold of a meter with Hz setting.
Find the Manuals up top under Quick links: Manuals.
