IGNITION
CIRCUIT

When

engine
does
not

start

If

there
is
no

problem
in
fuel

system

ignition
system
should
be

checked
This
can
be

easily
done

by

detaching
a

high

cable
from

distributor

starting
engine
and
ob

serving

of

spark

occurs
between

HYDRAULIC

The

the

pressure

elements

PRESSURE

SYSTEM

The

pressure
supply
system
consists

of

a

gear

type
oil

pwnp
driven

by
the

engine
through
the

The

The

to
the

upshifts

and

Vacuum
throttle
valve

The
vacuum

throttle
valve
transmits

regulated
pressure
based
on

engine

load
vacuum
This

pressure
controls

the

pressure
regulator
valve

Also
this

pressure
is

applied
to
one
end
of
the

shift
valves
in

opposition
to

governor

pressure
which
acts

on
the
other

end

of

shifts
a
restrictive
orifice

slows
the

while
the

is
allowed
to
release
This

prevents
a

Under

load
however
the

engine
will
tend
to

therefore
a
