    Hi Everyone,

    I hope someone can help. My Daisy would not start this morning and it turns out the Crankshaft Sensor has gone. Can anyone tell me where it is located as the RAC could not find it?

    From the workshop manual, page B8-25:

    In order to detect the engine revolution, a signal rotor is installed to the camshaft pulley. The engine
    revolution sensor is provided at theair intake side front of the cylinder head.
    When the camshaft pulley makes a turn, the air gaps between the engine revolution sensor and each of
    four protrusions on the signal rotor and one protrusion for the cylinder identification change. This change
    in the air gap changes the magnetic flux, thus generating pulses.
    The engine revolution speed is calculated by using the interval of the pulses generated by the four
    protrusions for detecting crank angle.
    The position of a pulse which is generated next to the pulse generated by the protrusion for the cylinder
    identification is detected as the point of the top dead center under compression stroke of the cylinder
    No.1.

    Thanks for your reply, hopefully I can find it from this.
