DESCRIPTION

The

ignition
unit

utilizes
a
semi

conductor
IC
device
and
is

mounted

This
circuit

detects

This
circuit

cuts
off
the

ignition

coil

primary
current
when
the

ignition

switch
is

and
the

engine

tionary

If
the

ignition
coil

primary
current

is

allowed
to
flow
under
such

condi

tions

excessive
current
will

be
drawn

because
of

WHEEL
BALANCE

The

should

be

kept
balanced

statically
and

dy

namically

Proper
tire
balance
is

necessary

when

driving
the
car
at

high

speeds

Consequently
the

wheel
and
tire

as

sembly
should
be

properly
rebalanced

whenever

puncture
is

repaired

The
wheel
and
tire

assembly
be

comes
out

of
balance
according
to

uneven

wear
Severe
acceleration

and

braking
or
fast

cornering
is

the

cause
of
wear
on
tire

resulting
in

unbalance
of
tire
and
wheel

assembly
