Electrical Systems Trigger Coil TestingGeneration III PVL Ignition Systems
All 2001 Carbureted The "trigger coils" are Hall Effect sensors and require constant DC power source via the brown wire out of the COl moduleThe wire is powered when the engine is cranked for starting and while running When magnet (sealed in the magnet holder on the flywheel) is passed by the sensor, the sensor becomes conductive and triggers the release of the energy stored in the capacitor, creating the ignition spark1To test trigger coils, disconnect the stator wires and attach volt battery to the brown and gray wires from the stator plateConnect one lead of an ohmmeter to the gray stator wireConnect the other lead to the red, greenor blue sensor wireRefer to the illustration at right2Rotate flywheel slowly while observing the ohmmeter indicationThe ohmmeter should indicate an open circuit (00) 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 to infinite as flywheel rotation continues 3Repeat the test for the other trigger coils PUR
