How do you check the ignition coils on a 1990 kawasaki 750 vulcan motorcycle?

hey.. the only way to check a coil of any kind is with an ohm meter,,,if it's bad it will show nothing or infinity... if it is good it should have at least 8 dependant upon the resistance but could be higher... i can't remember if too high means corosion or not but i know you can get the numbers from the manufacturer
