FLYWHEEL (RPM) SENSOR
The flywheel (RPM) sensor is mounted on the engine starter mounting flange adjacent to, but not touching, the flywheel
(backed off 1/4 turn).
The flywheel sensor is a device containing an inductance coil and magnet. When the magnetic field is distorted by the passing
ring gear teeth, the inductance coil generates an AC electrical signal that has a voltage and frequency variation proportional to
the engine RPM.
By monitoring the frequency of this signal, the controller can monitor the engine speed and precisely control the timing of the
starter disengagement.
If the flywheel sensor fails, the starter may not disengage or engage properly and a fault code will be generated.

Status – Flashes once per second when the base controller is powered and operating normally.
Flashes several time per second when flash loading. Is on without flashing during reboot and when
under test.
