The CDI Unit is powered by the AC current coming from the wrapped stator winding. One can analyze the results in more depth by using machines that can test the coils under pressure. Then it ran , after the swap I rode it a few times. Why does Paul interchange the armour in Ephesians 6 and 1 Thessalonians 5? Very good. We can test this function by interrupting the circuit that runs to the CDI from the coil and bridging this with a Lamp which is rated at 12volt/3Watt located in a lamp holder. Verified with ohm meter ,01 ohm for ground contacts. Ok, Im ready for some help. Can a rotating object accelerate by changing shape? 1.7 ohm I also tested the Pinout's pin 1. input from trigger .01 2 to ignition coil 0 pin 6. cdi power from stator. To diagnose your ignition system, you will need to do each of the steps in this article, in sequence. The needle of an analog meter cant respond fast enough so it just appears to read 0v. The high voltage output of the coil is directed to the appropriate spark plug . Reply here with your new readings. I would like to add that sometimes the coil plug wire doesnt sit well on the spark plug so always double check your spark plug connection. One really odd thing I see that seems like a problem is that the performance cdi I bought has a light on it and when the key is in the off position it lights up and when it is in the on or cranking position the light goes off. I dont understand where your getting your reading. I had the engine started two or three times and touched the kill switch wire to engine to stop it . You should have a resistance reading of at least 3-4.5 ohms. I have had someone holding the foot brake. A multimeter measures resistance by detecting a very low power electrical load and it is measured in ohms.
