Testing of the PVL ignition

Testing of the PVL ignition

Some of the PVL components can be subjected to a resistance test. A digital ohmmeter should be used to check PVL ignition components. Do not use an analog meter, because it is not accurate enough.

Note:
Check the components are not hot! You need to cool down the components to room temperature before you test!

Plug a test lead into the ends of the blue and black wires, after being out of the stator coil / disconnect the CDI module components. With analogue stators it does not matter which sensor is used on which wire. With digital stators can be a small yellow clamp, lift to insert the sensors into the clamps on the wire ends. Resistance values ​​less than or more than the recommended ranges indicate that the tested unit is faulty.

Note:
Check the ignition coil is directly on the ignition cable and not via the spark plug. Units can be operated easily with test scores above the recommended range. If the readings are within the lower range of the scale, however, the system works properly, the component should be replaced for safety reasons by a new one before total malfunction.
