Learn how to test a universal ignition module to determine whether it is in need of replacement.
- Universal Ignition Module (if replacement needed)
Set the multimeter to the 20k ohms setting. Place the red and black probes at opposite ends of the ignition module.
A reading of 4.54 kOhms indicates an as new ignition module. As the reading increases your spark’s power may decrease as an estimate resistances above 6-8K Ohms may cause failure of the spark needed to start a mower.
If resistance is infinite your module is damaged and will need to be replaced.
