    Hi Ken,

    No red light is obviously problematic. The sensor has three wires to it. 5vdc, ground, and speed sensor signal. Do you have 5vdc present at the sensor connector with system powered up?
    No?
    Check for defective cable between motor and connector.
    Yes?
    Try different magnet position relative to the senor. Or try reversing magnet end to end.

    Wow, just saw a great post by Sebz at the end of this thread... Give it all a read!
