12. Crankshaft position sensor
When the engine starts without dust or is difficult to start; poor acceleration and unstable idling; when the engine is stalled
intermittently, it is necessary to check whether the crankshaft position sensor is normal.
The crankshaft position sensor is installed on the right crankcase cover and integrated with the magneto stator. Locate the
sensor plug on the right side of the vehicle, press the head anti-trip lock and pull it out. Use a multimeter to measure the
resistance of the crankshaft position sensor① at 25°C (77F), it should be 150±20Ω, otherwise it should be replaced.
In addition, the three- hole plug of the stator② of the magneto uses a multimeter to measure the phase -to-phase resistance
of any two terminals at 25°C (77F), which should be 0.7±0.15Ω.
