Fig. 5 is way dumbed down, can't hurt, but doesn't tell the whole story. 2 colors, both clipped to battery, probe tip to Terminal 1, crank starter, red and green should alternate, green less bright than red. If this is happening and there's still no spark, the coil is N.F.G., power stage and it's input signal are fine.
The red in this test shows power flowing through the coil primary to an open circuit, green shows that circuit completed to ground. 2 color tester is the quickest, least expensive way to test here.
