Specifications
(800/1000 cc Models)
�� NOTE: The ignition system is a Normally Open Ignition (NOI).
* Main harness plugged in
Peak Voltage Tests were made at room temperature with the MaxiClips (p/n 0744-041), Fluke Model 73 Multimeter
(p/n 0644-191) set to the DC Volt scale, and the Peak Voltage Reading Adapter (p/n 0644-307). Also, the main
harness connectors must be unplugged (except on primary coil/CCU tests), the spark plugs removed and grounded,
and by pulling the recoil starter rope briskly.
��NOTE: Lighting coil output is unregulated voltage.

Peak Voltage Tests
(800/1000 cc Models)
��NOTE: The following tests should be made using
the Fluke Model 73 Multimeter (p/n 0644-191) set to
the DC Volt scale with Peak Voltage Reading
Adapter (p/n 0644-307). For “engine running” test,
use MaxiClips (p/n 0744-041).
��NOTE: Peak voltage test specifications are on the
Electrical Specifications (Individual) pages in this
section.
The Fluke Multimeter w/Adapter can perform the following
output tests.
A. Fuel Pump Coil
B. Injector Coil
C. Charge Coil (1) Output
D. Charge Coil (2) Output
E. Ignition Timing Sensor (1 and 2)
F. Primary Coil Output (MAG/PTO)
G. Lighting Coil Output
��NOTE: Peak Voltage Tests (unless otherwise indicated)
were made with connectors unplugged
(except on primary coil test), spark plugs removed
and grounded, and by pulling the recoil starter
rope briskly.
FUEL PUMP COIL
1. Test between the two orange wires in the fourprong
connector from the stator.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
INJECTOR COIL
1. Test between the two blue/white leads in the connector
harness from the stator plate.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
CHARGE COIL (1) OUTPUT
1. Test between the black/red and green/red wires in
the triple-plug connector from the stator.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
CHARGE COIL (2) OUTPUT
1. Test between the brown/white and green/red wires
in the triple-plug connector from the stator.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
IGNITION TIMING SENSOR (1 and 2)
1. Test between the blue/white (1) or the green/white
(2) and brown/green wires in the connector from
the sensor.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
PRIMARY COIL OUTPUT (MAG/PTO)
1. Connect the red meter lead to the orange/red wire
(MAG) or to the white/red wire (PTO); then connect
the black meter lead to the orange/black wire
(MAG) or to the white/black wire (PTO).
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
LIGHTING COIL OUTPUT
1. Connect the red meter lead to one yellow wire;
then connect the black meter lead to the other yellow
wire.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
LIGHTING COIL OUTPUT (@ 2000
RPM)
1. Attach the red maxiclip to the yellow lead; then
attach the black maxiclip to the brown lead.
2. Connect the red meter lead to the red maxiclip;
then connect the black meter lead to the black
maxiclip.
3. With the rear of the snowmobile on a shielded
safety stand, run the engine at 2000 RPM.
4. Meter reading must be within specification.
! WARNING
Most voltages generated by the ignition system are
sufficient to interrupt pacemakers! All technicians,
especially those using pacemakers, must avoid contact
with all electrical connections when pulling the
recoil starter rope or after the engine has been
started.
.is there an easy in the sled stator test.have a meter and looked at online service manual but im lost in space.hate to buy non needed parts.thanks
. I ordered from RM stator. Not to bad to change out.A Little tricky changing wiring harness from old stator to new one.About $210 delivery to my door better than $675 from Cat.
