measure the resistance of the crankshaft position sensor
①
at 25°C (77F), it should be 150±20Ω, otherwise it should
be replaced.
In addition, the three-hole plug of the stator
②
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.
