    Tacho calibration problem!

    Wonder if anyone knows an easy solution to this?

    I've got a tacho designed for a bike that I'm trying to fit on my pinto powered pop. Trouble is it shows double revs which I assume is because it's set up for a twin cylinder. It's a sealed unit so I can't get inside easily. Anyone know if there is some kind of device I could wire into the signal wire to make it read correctly????

    Hi Stan,

    I havn't seen him about on the forum tonight, but "sidspop" might be your man for this problem.

    Cheers.

    Hi there, looks like I have found you. Looking at it very simplistically, if your tacho is reading twice what it should, then you need a divide by two box of tricks. 2000 pulses in gives 1000 pulses out. But to be perfectly honest, I do not have a clue as to how to make one.
    I know James Murray is a bit of a whizz with electronics, and there may be others on here who could assist.

    Thanks Sid. Funnily enough just got back from Maplins and have tried their "solution".
    No joy with the resistors they supplied. As I have now managed to expose the dial I think I'll have to resort to some careful manipulation of the graphics!!!
