How do I test that the cdi is receiving the signal of engine rotation to then send the pulse to ignition coil? I have a 97 gtx 787 with no spark that is driving me crazy because everything checks out except for the no spark. i connected my 12v test light to the white wire on the ignition coil and get no pulse when the engine turns over. (engine cranks fine, two beeps, battery new). I have tested the ignition coil itself and it ohmed good. i have a feeling the cdi is out but have reached the maximum of my mechanical knowledge on how to test the pulse from the engine to cdi or how to diagnose a faulty cdi. Thanks.
