    Default Tohatsu M5A

    Hey Guys,I am new here,please correct me if I am wrong.

    The Pic is the coil assembly from a Tohatsu M5A that was last used by Noah on the ark I think.

    I assume that A is the primary coil and that B is the secondary coil.
    I t also looks like coil B is shot but I have been wrong before.

    i have a tohatsu 9b9. i also thought my coil was bad but after cleaning the points the spark came back.Try this first it could save you lots of time.

    Oh by the way judging by the photo you have a primary and secondary winding all in one, this is B in the photo. I dont think A is a coil and the gap on the points seems too wide. So clean the points close that gap and without tightening the flywheel down you should be able to spin the flywheel enough to see a spark.
