STARTER CHARACTERISTICS
The starter
consists
of
the
following
main parts:
a solenoid,
with
a core which, because
of
the
action
of
the magnetic field, induced by the
solenoid coil, moves axially
to
carry on
the
following; exerting pressure on the return
spring, positive engagement
of
the
pinion
with the flywheel gear ring through a special
lever,
connection
in
circuit
of
the field win·
ding fixed contacts, hence
allowing
the
passage
of
the energising current necessary
to operate the starter.
