Those digital meters can be confusing and misleading, especially if you don’t have them set correctly. When you say “no reading”, I am assuming you mean infinite ohms or an open circuit. I am assuming that the green wire is the coil primary lead and the black wire is the coil ground, common to the primary and secondary leads. The proper way to test the secondary circuit is to touch one lead to the coil ground lead, the other lead to the plug terminal, this should show several thousand ohms. Touching one lead to the coil ground lead, the other lead to the coil primary should show about 1 ohm. Needless to say, your meter must be set properly or you will misinterpret the results. You may want to try testing the other coil first and compare the results before buying a new coil. Keep in mind, that even a coil that reads correctly on an ohm meter may be defective, especially if the secondary has an external leak/crack allowing arcing to ground.
