    GP12 charge coil causes no spark?

    Because the Yamaha service manual has no definitive answer, will a bad charge coil cause a no spark condition? The black/red-blue test shows no resistance. The pulser coils all test out good. Thanks.

    If the charge coil is bad you will not get spark, I have had this issue before.

    Yes the charge coil charges the CDI not the battery.
