If an OL (no continuity) is obtained on any one of

the three tests, replace the rectifier/regulator.

Stator

NOTE :

If vehicle is equipped with a single phase stator,

complete the steps described, but omit the

references made to the third wire (three phase

stator).

Static Test

1. Disconnect the stator connector.

2. Set multi meter to the lowest Ohms setting.

Measure the resistance between all three wires

coming from the stator. Start with one wire and

read resistance between it and the other two.

Repeat for remaining two wires.

If all readings are within 0.5 to 2.0 Ohms, go to

the next step.

If one of the readings is lower than 0.5 Ohms or

higher than 2.0 Ohms, replace the stator.

Connect one of the multi meter leads up to one of

the three yellow wires. Connect the other multi

meter lead up to the crankcase or to a grounding

point on stator core if it has been removed. Check

the reading on the meter. Make sure the connec-

tion of the lead to the crankcase or stator core is a

good one.

No reading or “OL” displayed, go to the next step.

If you have any reading between 100 Ohms and

zero Ohms, replace the stator.

Dynamic Test - AC Output

1. Switch the multi meter to the AC voltage (range at

least 100 VAC). Make sure you do not switch to

DCV or Vdc by mistake. Connect the multi meter

leads between two of the yellow wires emerging

from the stator. Start the engine and bring to 5000

r/min. Check the reading on the meter. Switch one

of the multi meter leads to another yellow wire

and check the reading again.

If three equal readings are obtained, all higher

than 50 VAC, the stator is ok. A problem may

exist in the rectifier/regulator. Test the rectifier/

regulator.

FLYWHEEL

Inspection Points

1. Check for contact between the installed flywheel

and crankshaft position sensor. Make sure the

specified sensor air gap is maintained throughout

flywheel rotation.

SERVICE:

1. Inspect the flywheel for cracking, damaged

magnetic material, key groove, and woodruff

(crankshaft) key.

2. Check flywheel key location. Make sure the hub

has not spun in the aluminum body. The key “cut”

in the hub should be aligned with the “C” in the

molded “Cannondale” text.

START BUTTON (ATV & MOTORCYCLE)

1. Disconnect the engine start button from the main

harness.

2. Test for continuity between the two leads. There

should be no continuity.

3. Press and hold the button and test for continuity.

There should be continuity when the button is

pressed.

ENGINE STOP BUTTON

1. Disconnect the engine stop button from the main

harness.

2. Test for continuity between the two leads. There

should be continuity.

3. Press and hold the button and test for continuity.

There should be no continuity when the button is

pressed.
