Trigger Coil (Hall Effect Sensor) Testing
The ''trigger coils" are Half Effect sensors and require constant DC power source via the brown wire out of the COl module The wire is powered when the engine is cranked for starting and while runningWhen magnet (sealed in the magnet holder on the flywheel) is passed by the sensor, the sensor becomes conductive and triggers the

Rotate flywheel slowly while observing the ohmmeter indication The ohmmeter should indicate an open circuit ((XI) until the magnet in the magnet holder passes by the sensorAt this point the reading should switch to low resistance (under 25 ohms)It should go back 10 infinite as flywheel rotation continuesRepeat the test for the other trigger coils
