Its been 4 years since i worked on the little kawi in the old gator so my memory is a little foggy haha. I do remember the module needs 12 volts power when the key is on. It also has a kill wire to disable spark when key switch is off. The pulse coil charges the capacitors inside the module and best i remember there is a small magnet for top compression stroke to fire the spark. I would make sure power is applied to module and kill wire is not grounded. also a good battery is required to spin the engine fast.
