Well the coil arrived today so it tested it on bench, .80 ohms on tab to tab and 14.2 wire to wire. All was steady when tapping lightly and tipping side to side. Installed and no spark. Went back to basics and did some more reeding. I am hearing the CDI gets its signal from the coil trigger in the mag and the CDI is what sends the voltage to the coil. Is this true?. I tested with digital volt meter and when lanyard is on and I get the two beeps and I am getting 11.3 volts to the white wire on the coil. When I turn the engine over it goes down to .3, and stays there steady while cranking. When I stop cranking it jumps back up again. Is this telling me the trigger is working in the mag but the CDI is not putting out? I really dont want to take the cover off if i do not have to. Does the mpem have any control on this white wire also? So my questions are;
1. Does the CDI gets its signal from the coil trigger in the mag and does the CDI send the voltage to the coil via the white wire?
2. If I get 11.3 volts at the white wire on the coil with power on and non cranking, and then when cranking I get .3, what is this telling me?
3. Does the mpem control the voltage to the white coil wire?
4. Am I correct in saying I should get a high/low reading when testing volts on the white wire on the coil when cranking.
Thanks for taking the time answer some questions
