https://stream.echo6.co/videos/watch/8f3232e6-fa9e-4e26-8d18-6a3242e8a499 Another economically made module from the wiring loom of a Chinese quad ATV or scooter. This module interfaces between the magneto/alternator and the ignition coil to provide high current pulses in sync with the engine. The use of a high voltage winding on the alternator/magneto is to store as much energy in the 1uF capacitor as possible for dumping through the ignition coil in pulses to induce a high voltage spark. It's a very simple circuit, but this one has some odd quirks compared to others. Is the input RC arrangement to provide a speed dependent timing variation for the spark? Is it normal to short circuit the high voltage winding of the alternator on each alternate half wave? Anyone had a shock from the appropriately named "kill circuit" on the keyswitch or engine switch? Let me know what you think in the comments.
