How the Ignition Module Works
The ignition module works with the engine's flywheel and ignition system to generate the electrical energy needed to create a spark at the spark plug.
As the flywheel rotates, the ignition system generates an electrical pulse. The ignition module controls this process and produces the high-voltage output needed for ignition.
A properly functioning module is essential for reliable combustion and engine operation.
Signs of a Faulty Ignition Module
A damaged ignition module may cause:
-
Engine will not start.
-
No spark at the spark plug.
-
Intermittent starting.
-
Engine starts and then stops unexpectedly.
-
Engine misfires.
-
Engine loses power or runs inconsistently.
-
Spark disappears as the engine warms up.
Before replacing the module, check the spark plug, ignition lead, connections, stop-switch circuit, and flywheel/air-gap condition, since these components can also cause ignition problems.
Why Replace the Ignition Module?
A failed ignition module can prevent the spark plug from receiving the correct ignition voltage, resulting in a no-start condition or unreliable engine operation.
Replacing it with the correct STIHL OEM 4139 400 1302 Ignition Module helps restore the original ignition-system function and reliable spark generation.
