DESCRIPTION

The

unit

utilizes
a
semi

conductor
IC
device
and
is

mounted

on
the

side

This
circuit

detects

sent
from
the

circuit

This
circuit

cuts
off
the

ignition

coil

primary

when
the

ignition

switch
is

ON
and
the

engine
is

sta

tionary

If
the

ignition
coil

primary
current

is

allowed
to
flow
under
such

condi

tions

excessive
current
will

be
drawn

because
of

efficient

operation
of
the

IC

unit
these
five

circuits
are

manufactured
in

assembly
as

except
the

and

the
circuit
is

arranged

ceramic

substrate

together
with

REMOVAL

It
is
much
easier

to
remove
