Diesel Revcounter

Anyone help me locate the sender on the Diesel Engine please?

The illusive Tacho as informed by Mat (I think?) is not working when it gets warm. So if I know what I am looking for either clean it up if possible or get a new one.

I gather the petrol ones work differantly so that plan of using the one off the TRS has gone out the window.

You putting it back in now Mat.
There was none on my old 87 RD. That's why when I stuck the motor in the Meteor, it ended up with no Tacho...or is that something Mexican to eat

I think they're made up of a coil encased in plastic, in which a small current is generated when the flywheel passes it. So physically cleaning it I wouldn't think would help - you could measure the resistance of it and if it's gone open circuit then bin it. More likely it will give a resistance when cold, and then as it expands when warm the circuit will be broken.

Or in other words, no.
