    I have an '03 Ultras Classic, and it has some intermittent electrical problems.
    1. The speedo is erratic...needle bounces around, and sometimes drops to
    2. The turn signals do not cancel, again intermittent.
    3. The engine, at times will not idle, also intermittent.
    4. The cruise control is sometimes erratic.
    5. Occasionally, the engine will cut out for less than a second, but will
    resume running, and go along OK...this may happen 2 or 3 times on an
    extended day ride.

    I have replaced the speed sensor, located in the transmission, but it has not changed the problems in any way. I have also verified good voltage to the speedo and sensor at pins 8 and 12 for the speedo and pins 10 and 11 for the speed sensor. I'm at a loss at this point...do you think it could be the speedo itself, as the speed sensor signal looks like it passes through the speedometer, before going to the ECM, and cruse control. Any help would be very much appreciated.

    If you have changed the obvious VSS, then check out the back of the ignition switch for corroded/loose terminals.
