Rev counter?

[serenitycamper]

Is it possible to fit a rev counter to a 1y engined t25? I need to know what revs I'm doing urgently as they sound silly high. If so how do I do it electrically?

Thanks
Rich

From the 'W' terminal on the alternator - if you have one. (you can take an a/c signal from one field coil before the diodes - details are out in t'internet if you haven't) There are also other methods such as optical pick up from a rotating black and white disc and ones that clamp on an injector pipe and pick up the sound of the pulse of diesel in it.

Thanks for the info, I'll see what I've got to work with
