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 LH 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.
