    Also did the following tests.

    This is what I came up with

    Pulser
    White/Black & White/Green =.360K
    White/Red & White/Yellow =.362K

    Charge
    Brown & Blue =1.111K
    Blue & Red =137.7

      I would suggest testing the inputs to the CDI assembly first. If they are out of spec, get those fixed.

          No. Testing them separately.

          For instance, the manual giveS a specification for the pulser coilS. Disconnected from the CDI. Do the pulser coils meet the specs? Are the coils not grounded?

              Yes. Those are the reading I posted in the comments. The only reading that doesn’t seem too positive is the stator wires are not completely open when testing to ground
