The starter
motor is rated as a 1.8kW and is a Denso level three-sealed unit. It is an RA
type starter motor, which is of the offset design with the solenoid being
directly behind the pinion to give a more positive engagement to the ring gear.
The motor is geared directly to the pinion. Each starter motor is of the
pre-engaged type and comprises of a series wound motor and an overrunning
clutch. This starter incorporates labyrinth-breathing tubes to help with sealing
and drainage.
The starter solenoid is energised by a signal from the ECM
when the ignition switch is moved to the crank position. When engine cranking is
requested, the ECM checks that a valid key code has been received before
granting the crank request.
The power for starter operation is supplied
on a substantial single cable connected direct from the battery positive
terminal. The cable is connected to the solenoid via a copper threaded stud with
an anti-rotational device and secured with a nut.
The starter motor is
located on the rear RH side of the engine block. The motor is secured to the
block and protrudes through an aperture to drive the flywheel via a ring
gear.
