Testing Low Oil Light
Sending Unit
The
low
oil light sending unit is a magnet ic
switch.
Its
operat ion
is
based on a doughnut
magnet located around the
inside
diameter of a %
in.
ho le in
a
plastic float. The switch,
located
in
the stem of the
send
ing
unit,
is
positioned
through
the ho
le
in the float. When the float drops
to the lower part of the stem, the magnet c loses
the electrical contacts
(located in
the
stem)
allow-
ing current to pass on to the
li
ght in the console.
If the
sending
unit
shou
ld fail,
it
must be replaced.
To test the
sending
unit, use the follow ing pro-
cedure:
1.
Remove
the
sending unit from the oil tank by
tw isting and pu
ll
ing upwards. Wipe oil from
the sending unit with a c loth.
2.
Unplug the

Using
an
ohmmeter,
set
the
scale
selector
knob on X1 K pos ition.
4.
Touch each of the meter
leads
to one of the
two wires coming from the sending unit. With
the sending unit in its normal position
(float
end down), the meter should read CLOSED.
5.
If the meter
reads
OPEN, double check to
make sure you have made good contact with
eac~
of the wires coming from the sending
unit.
If
the meter
st
ill
reads OPEN,
replace
the
sending
unit.
6.
While maintaining contact between
the meter
leads and the sending unit, raise the float up.
The
meter must read OPEN. If
the
meter reads
CLOSED, rep lace
the sending unit.
7.
If
the sending unit
tested
out
satisfactory
but
the light
in
the console doesn't illuminate
wit
h only
a
small amount of oil in the oil tank,
check the bulb in the console.
8.
If the bulb is
in
good condit ion, check for
voltage at the connection where the send ing
unit plugs into
the
wiring harness. Using a
vo
lt
meter set on the 50 ACV sca le, start
t
he
eng
in
e and allow it to id
le.
Touch the red lead
of the vo ltmeter to the
red
wire in the two
prong connector. Touch the black lead
to the
black lead
in
the wir ing harness. At idle, the
meter should read 5 to 6 volts (AG). If no
voltage
is
present, but the lights on the
