2006 450 Sportsman won't start after it been running awhile

[Okiechoctaw]

Just wanting to see if any one has dealt with this before. I belive its losing spark after its been shut down from running for awhile ive got to wait about an hr an it will fire back up. I'm in the process of trouble shooting now.

Definitely no spark when hot, does any one know how to test strator ?

Here is what found to test the strator will give it a go tomrrow 

Exciter Coils Testing

 

 

 

1. Follow the electrical harness from the alternator to the location where it connects to the CDl unit

 

 

 

2. Disconnect the three-pin electrical connector from the CDI

 

 

 

3. Connect an ohmmeter between the following wires in the three-pin stator connector and compare

 

the resistance to the specification in Table 1.

 

a. The red and green terminals.

 

b. The black/red and green terminals.

 

 

 

4. Replace the stator assembly if the resistance is not as specified.

Alternator battery Charge Coils Testing

 

 

 

1. Follow the electrical harness from the alternator to the location where it connects to the voltage regulator.

 

2. Disconnect the two individual yellow and the yellow/red electrical connectors from the voltage

 

regulator.

 

3. Connect an ohmmeter to the wires indicated in Table 1 and note the resistance .

 

4. Replace the stator assembly if the resistance is not as specified.

 

5. Apply dielectric grease to the electrical connectors and reconnect them.

Alternator Output Test

 

 

 

1. Follow the electrical harness from the alternator to the location where it connects to the voltage regulator.

 

2. Disconnect the two individual yellow and the yellow/red electrical connectors from the voltage

 

regulator .

 

3. Connect an AC ammeter to the yellow and the yellow/red stator wires leading from the alternator.

 

4. Shift the transmission into neutral.

 

 

 

CAUTION

 

Do Not start the engine with the electric starter; as the ammeter will be damaged.

 

 

 

CAUTION

 

Do Not conduct this test for longer than 10-15 seconds, as the. the alternator windings may overheat.

 

 

 

5. Start the engine with the recoil starter and let idle.

 

6. The specified amperage is listed in Table 1.

 

Replace the stator assembly if the amperage is not as specified.

 

7. Apply dielectric grease to the electrical connectors prior to reconnecting to help seal out moisture.

Did you ever get this fixed?  Was it the stator?
