IGNITION COIL 32140-93900

Function and technical context

The ignition coil is the component responsible for transforming the battery voltage into the high voltage necessary to generate the spark in the spark plugs, being the heart of the ignition system in two-stroke outboard engines. It works within the electronic ignition circuit, collaborating directly with the CDI module and the magnetic flywheel to synchronize and enhance each electrical discharge at the exact moment of the combustion cycle. A failure in this coil causes difficult starts, intermittent misfires or the complete inability to start the engine, leaving the boat without propulsion. The reference 32140-93900 is manufactured according to the manufacturer's specifications to guarantee the correct functioning of the ignition system in the Suzuki DT9.9 and DT15 models.

When to replace this part?

The most common symptoms of a damaged ignition coil are: difficult or impossible starting when cold, jerks and power losses at variable speeds, sudden engine shutdowns and weak or absent spark when checking the spark plugs. It is recommended that the ignition coil be inspected at each seasonal inspection and replaced if there is any sign of carbonization, cracks in the winding, or out-of-range resistance readings on the multimeter. Changing it preventively at the first symptoms avoids being left without propulsion at sea and reduces the risk of secondary damage to the CDI module or other components of the ignition system.
