TESTING
WITH
.
AN
OHMMETER
An
accurate
way
to
test
glow
plugs
is
with
an
ohmmeter.
Touch
one
prod
to
the
glow
plug's
wire
connection,
and
the
other
to
the
body
of the
glow
plug,
as
shown.
A
good
glow
plug
will
have
a
0.9
ohm
resistance.
This
method
can
be
used
with
the
plug
in
or out of the
engine.
You
can
also
use
an
annneter
to
test
the
power
drain
(13
amps
per
plug).
Re-install
the
plugs
in
the
engine
and
test them
again.
The
plugs
should
get
very
hot
(at
the
tenninal
end)
within
5
to
10
seconds.
If
the.plugs don't
heat
up
quickly,
check
for
a
short
circuit.
When
reinstalling
the
glow
plugs,
use
anti-seize
compound
on
the
threads.
A
CAUTION:
Do
not
ke~pgi~
plug
on
