amp gauge for the test.
Replace
the wires
after
the test is completed.
Disconnect
the shift leads at the rear of
the engine.
Temporarily
lay a piece of cloth
or other insulating
material
under the wires
to
prevent
them
from
shorting
out during
the following tests.
Again operate
the
shift
lever
and note
the current
loss.
If the current
draw is still
more
than
2.5 amperes,
then
check
for a
short in the control box switch or wiring.
If
the
current
draw is normal
with the leads
disconnected
from
the
engine,
then
check
for a short in the gear case coilts) or wiring.
If the coil leads are shorted
to each other,
both shift coils would be energized,
stalling
the engine or causing serious damage
to the

3- Shift Coil Tests
Testing the shifting coils is accomplished
by first disconnecting
the wires at the rear
of the engine.
Next, connect
an ohmmeter
first
to one shift
coil lead and ground, and
then
to the other
in the same
manner.
A
reading of more than
1+.5
to 6.5 ohms indi-
cates a short in the coil or lead.
No reading
at
all
indicates
an open
circuit.
If the
results
of this test
indicate
a short
in the
cirucit , the lower unit must be disassembled
and inspected.
See Chapter
8.
4- Testing Shift Switch -
Forward
To test
the
switch
for
the FORWARD
position,
make contact
with one probe of a
continuity
meter
(or a test
light)
to the
terminal
(purple
or
red
lead)
and
to
the
forward (green lead) terminal
with the other
probe.
Now, move the
shift
lever
to the
FORWARD position.
The meter should indi-
cate continuity
(or the
test
light come on),
ELECTRIC GEAR BOXES
7-13
when
the
shift
lever
is in the FOR WARD
position.
5- Testing Shift Switch -
Reverse
To test
the
shift
switch
for
reverse,
make contact
with one probe of a continuity
meter
(or test
light),
to the terminal
(pur-
ple or red lead) and to the reverse
terminal
(blue lead) with the other probe.
Move the
shift lever to the REVERSE position.
The meter
should indicate
continuity
(or
the test
light come on), when the lever is in
the reverse position.
6- Testing Shift Switch -
Neutral
After the forward
and reverse
tests have
been
completed
check
for continuity
with
the
shift
lever
in the
NEUTRAL position.
Leave the red lead connected
and check the
blue
lead
(REVERSE) and
the
green
lead
(FORWARD).
Continuity
should not be indi-
cated when the shift handle is in NEUTRAL.
