    are you testing directly on the coil’S HV output pin ?

     

    have  you  verified the  boot’s   internal connection …to the plug wire

    try testing the coil secondary with a VERY SMALL needle  stuck in the plug wire … maybe the problem is just  at the boot end of things.

    reseal  the  small pin prick with a dab of silicon.
