Let me know your resistance number, and well move on to the next step. With cdi plugged up I get no lights horn anything. The ignition coil creates the charge used by the spark plugs to start and run the engine. No wasted spark. If the stator came with the pulser coil. Are you testing the Red/Black wire for AC voltage, or Ohms? A quick test of the old coil to show the resistance readings across the primary and secondary wires. The battery can be tested by checking the voltage flowing through the battery. Minimum values: Bill, are you using a digital multimeter to test your stator, or is it an analog type (with needle)? One other thing, the first time that I tested the stator ignition coil, it was still connected to the cdi unit, and the VAC reading was much lower, is that normal? I have changed CDI stator and coil any ideas would be extremely helpful. Within the world of stators, there are permanent magnet systems and field excited stators. Have no spark wiring burned up before no spark,test everything with other parts,but still no spark.What could be wrong with it? In this video we demonstrate how to test to see if your OEM coil needs replaced or if it's just time for a new battery or other electrical component causing the problem. Yes, I bypassed the switches and grounded pin 5. The most sensible place to begin is with your car in park, and the engine switched off. 2.99. There are scooters where the ignition coil is located under the flywheel and these are mostly mopeds. He farmed commercial garden produce for several years. It was my KEY SWITCH.
