Re: Johnson 25 powerpack
CD Ignition description, probably more than you really want to know:<br /><br />"The magneto Capacitor Discharge (CD) ignition system consists of five major components. They are:<br /><br />1) Flywheel Assembly Contains two magnets, cast into the flywheel 180 degrees apart. These magnets are magnetically charged of opposite polarity.<br /><br />2) Charge Coil Assembly A large coil of wire which generates Alternating Curent (AC) that is sent inot the Power Pack.<br /><br />3) Sensor Assembly A small coil of wire which generates the triggering voltage for the Power Pack.<br /><br />4) Power Pack Assembly Contains the electronic circuits necessary to produce ignition at the proper time:<br />a. Capacitor charge circuit<br />b. Triggering circuit<br />c. Capacitor Discharge circuit<br /> <br />5) Ignition Coils Generate the very high voltage required to ignite the fuel in each cylinder."<br /><br />Source unknown, that's my story and I'm stickin' to it.<br /><br />With all that being said, when my powerpack went out, it failed completely and absolutely. No partial failure at high-speed or anything. Absolutely no spark from either plug wire.
