Although, my stator wire bundle is 100% within a block I have no bullet style plugs. No reading on trigger. The main tools you will need to do these tests are 1) The Service Manual for your particular bike 2) an inexpensive multi-meter to measure ohms of resistance. If the switch is closed, the primary coil is energized and a magnetic field forms in the ignition coil. Trigger is putting out 0.1 VAC Connect and share knowledge within a single location that is structured and easy to search. Stator Test. My gy6 does not spark while cranking, but just as I let off the key it fires. (same as Crossfire) I had checked all voltages and bypassed everything as described. Is this a symptom of other issues?? fist we replaced the sator rings worked really good first few days then stop working. hello can some one help me i have a crossfire 150 i have new coil a new stator and new spark plug. Can you help me? Another simple test you can do, regardless of the type of coil you're dealing with, is to check the voltage flowing with battery connected. Replaced rectifier.
