    Hi all,

    I recently bought a 406 1998 1.9TD.

    Symptoms:
    -Rev-meter doesn't move when engine is running.
    -The only time it moves is when I turn the key to start the engine (it
    rises to red-line momentarily and then drops back to zero)

    My thouhts:
    -Since the rev-meter moves during ignition, I presume that all the
    connections are ok.
    -I've checked all the fuses

    I've tried looking in Haynes, but it doesn't seem to mention the rev-meter
    anywhere in the normal sections of the book. Does anyone know where the
    rev-meter is connected to? is it the gearbox, or is it the ECU? I can't
    make any sense of the wiring diagrams in Haynes.

    Thanks,

    Tachometers on diesels used to normally take a feed from the alternator.
    Whether newer ones like yours use a crank sensor or the ecu I couldn't say but
    I'd check the alternator connections first.
