Reluctor settings If you are using the reluctor circuit, adjust VR2 fully clockwise and measure the voltage at pin 6 of IC1. If the voltage is close to 0V, wind VR2 anti-clockwise several turns until the voltage goes to 5V. That done, wind it about two turns more anti-clockwise and leave VR2 at this setting. If the voltage is 5V when VR2 is fully clockwise, rotate VR2 fully anti-clockwise and start to wind it clockwise until the voltage goes to 5V again. Then wind it two more turns clockwise. That done, switch off the ignition and connect Q1's collector wire to the ignition coil's negative. Starting Now try to start the engine. If it doesn't want to start, the sensor signal may be inverted. This can happen with Hall Effect sensors and optical sensors if the output voltage goes low at the point of firing. In this case, change link LK1 to the "invert" position. The reluctor circuit is designed to fire the coil when its output voltage swings negative. If the engine doesn't start and you are using a reluctor, try swapping the reluctor connections.
