I tested across the blue and yellow stator wires that go to the cdi units and got no voltage. Should read 180v with a dva adapter. I have spark on cylinder 2 coil. No spark on cylinder 1 or 3. I believe cylinder 1 coil is bad. I'm confused, HELP!!
 
To test the coil: you know the other coil is sparking so swap the position and see if the spark follows the move?
No fire on any cylinder: 1. Check the resistance from each blue to the yellow wires, you should read approximately 300 ohms. 2. Check the resistance from each blue and yellow wires to engine ground, you should read open circuit (Just like the leads were not touching anything). 3. Check DVA (Peak voltage) from blue to the yellow wires, you should read at least 180V. 4. Check the DVA (Peak voltage) from each blue and yellow wires to engine ground, you should read no voltage or extremely low voltage. No fire on one cylinder: 1. Check the resistance from the blue to the yellow wire on the pack not firing, you should read approximately 300 ohms. If the resistance is not right, check the other set of wires. If the other set is ok, gently pull on the wires close to the connector. If the insulation stretches, the wire is broken inside the insulation and a new terminal needs to be put on. 2. Check DVA (Peak voltage) from the blue to the yellow wire, you should read at least 180V. 3. Check DVA (Peak voltage) from the Blue and Yellow wires to engine ground. The readings should be approximately the same. If the readings are very different, disconnect the connector going to the pack with the low reading. If the DVA from the Blue and Yellow wires to engine ground on the other pack is now checking correctly, the pack you disconnected is likely bad. On a 2 cylinder engine, swap the Blue and Yellow wires and see if the problem moves to the other cylinder. If it does, the stator is defective. If not the pack is likely bad. NO FIRE ON TWO CYLINDERS: If two cylinders from the same CD unit will not fire, the problem is usually in the stator. Test per no fire any cylinder above. If the #1 and #3 cylinders are not firing, disconnect the Brown/Yellow wire from the pack #1 and retest. If you now get fire on #3, replace the #1 pack. If still no fire on #3, disconnect the Brown/Yellow wire from the pack #2 and retest. If you now get fire on #1, replace the #2 pack. If the #2 and #4 cylinders are not firing, disconnect the Brown/Blue wire from the pack #1 and retest. If you now get fire on #4, replace the #1 pack. If still no fire on #4, disconnect the Brown/Blue wire from the pack #2 and retest. If you now get fire on #2, replace the #2 pack.
