Thread: Faulty RPM Board

  1. #1

    Faulty RPM Board

    Hi all, after starting my engine (Aerosport Power O320 with dual Lightspeed Plasma II+ ignition) I always turn each ignition off to make sure they're both working. Turning ignition 1 off everything is as expected however when I turn ignition 2 off the RPM indication on my AF3500-non S screens goes to 0 while the engine keeps making noise. That tells me the ignition systems are fine and I have an indication problem.

    When I swap the red and yellow wires over the fault 'moves' from being with ignition 1 to ignition 2, which tells me the fault is on the RPM board.

    How do I go about getting a replacement board?
    Cheers
    Steve

    Give us a call at 503-263-0037 x 2 and let us know you need an 71420 RPM Board for your dual Lightspeed Plasma II+ ignition.

    PII+ has a really fast pulse of 300ms @ 10V as its
    RPM signature so sometimes noise is an issue. Do you have the RPM shielded per their manual?
