    Alternator conversion and tach

    Next weeks project is removing the generator and installing an alternator in my 100-6 bn4. What must I do to convert my tach? Iím negative ground, Pertronix ignition.
    thanks,

    BN4 should be mechanical tach - nothing to change.

    Be sure to reverse the tach cable for negative ground.

    Cute!

    Hey Larry, have you considered conversion to Dynamator? It looks like a C45 type generator but with alternator (Bosche?) internals but not much installation modification. Mine provides constant 14.5V charging at around 1000 RPMs and 45 amps. They're perfect for more than basic Healey applications GONZO.

    Bob, I thought I just turned the tach upside down?
