switch
and connect the ohmmeter
leads to
each of
the probes on the back of
the switch. If the meter reads OPEN
(with
switch
in ON position), replace the switch.
If the meter reads CLOSED, proceed to

k
to be
sure
throttle cable is
properly tensioned
by
compressing
the
throttle lever and
if needle goes from OPEN
to
CLOSED,
throttle-cable slack must be re-
moved
.
If the meter reads OPEN, replace
the
throttle
control.
If the meter reads
CLOSED,
the problem
is in the main wiring
harness; therefore, replace the main wiring
harness.
Testing
Ignition
Coil Output
Before testing ignition coil output after testing
the main wiring harness and safety switches,
all wiring harnesses must be connected. Also,
check to be sure all switches (ignition switch
and emergency stop switch) are in the ON
p~si
tion. Ignition coil output may be tested by using
either one of the following procedures:
•
To test ignition coil output using the
Elec~ro
Specialties Model 1 L tester, use the following
procedure:
ill
WARNING
ill
For sat ety purposes raise the rear of the
snowmobile off the floor using a shielded
sat
ety
stand.
.
1.
Remove the resistor spark plug from the
MAG-side cylinder and the spark-plug cap;
then
install
an NGK B8EV plug with a non-
resistor-type spark-plug cap (or a metal
con nectar).
2.
Connect the MM-1 adapter to the spark-
plug wire. Attach the red tester lead to the
•
engine.
CAUTION
Spad< plugs must be instaDed
or
da111ag1
to
the
cails
and/or COi unit
may
flSR.lh.
3.
Set the tester on 80 HIGH scale. Crank the
engine over quickly. If the tester light il-
luminates, output is satisfactory. If the
tester light fails to illuminate, proceed to
Testing CDI Unit Output. Test 3 times for
conclusive results.
To visually test
ignition
coil output, use the
following procedure:
1.
Remove the spark plugs from the cylinders;
connect to the high tension leads and
ground on the cylinder head(s).
2.
Crank the engine over quickly and inspect
for a bright blue spark. If a bright blue spark
is present, ignition coil output is satisfac-
tory. If no spark is present, proceed to
Testing COi Unit
0utput.
