Product Overview
GM39600 Crankshaft Position Sensor for Kohler & Rehlko Marine Generators
The GM39600 Crankshaft Position Sensor is a crucial component for the precise operation of your Kohler or Rehlko marine generator. This sensor is instrumental in the engine's ignition and fuel injection timing. It accurately monitors the position and rotational speed of the crankshaft, sending vital data to the generator's Electronic Control Unit (ECU). This precise information enables the ECU to deliver fuel and spark at the exact correct moment, which is essential for the engine to start and run smoothly and efficiently.
If your Kohler or Rehlko marine generator cranks robustly but consistently fails to start, a malfunctioning GM39600 Crankshaft Position Sensor is a very common cause. Without an accurate signal from this sensor, the ECU may not be able to properly time the spark or fuel delivery, resulting in a frustrating no-start condition, even though the starter motor is engaging the engine. Replacing a failed crankshaft position sensor can often directly resolve this issue, restoring your generator's reliable power.
