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.spacer.png

      Baja 250, No Spark , I'm stumped ...
      By Mhatayas
      My uncle bought a Baja 250, 2006. Knew there was no spark since the get go. He don't know anything about quads so is getting me to help him try to get it running...
       
      battery is bad so I connected battery charger to it to crank it over , cranks over well , but no spark .... 
      Lights and everything work fine , but with each crank over using the e start switch , the display reads 999 888 777 666 ... Right down to 000 and repeats itself . 
       
      He managed to get a parts bike , I changed over the CDI and the coil and the stator from the parts bike and there was another black box by the voltage regulator I changed over ... I used my multimeter to confirm as much as I could works , it's hard without knowing which wires are which , and I cannot find any diagrams online for this bike ? 
       
      Do you think it could be the Killswitch? There's so many wires coming from there I don't know where to start . Also I should mention it appears the fan on the front of the bike has been taken off (the wires have been cut too ) 
       
      If this bike sparked it would run . The previous owner said he parked it one day and it just wouldn't start after.

      1998 Big Bear running lean, real lean.
      By Bobbywolf
      I am working on a basket case for a friend.  It is a 98 Big Bear (YFM350FWB).  It came with a parts machine which is a 96, which I am coming to find out is VERY different from his machine.
       
      Anyway, first thing is first.  I checked compression, 150psi.  Valves are set correctly, and the engine is in time.  I cleaned the carb, and there was some junk in the passages.  It is a chinese carb, which I figured from the lack of markings or lettering altogether.
       
      The bike runs.  It idles ok, but breaks up badly under acceleration.  Pulling a new spark plug shows it is running lean.  White strap, with no black whatsoever.  So I have the carb adjusted with the mixture screw out way too much (about 5 turns), and the diaphragm needle lifted to the top slot.  It is still not getting enough fuel (or too much air).  It backfires through the carb, and cannot get above idle without carrying on.  The carb boot is in good shape, so it isn't pulling any air there.  I did test this as well by spraying ether around the boot when running, looking for intake leaks.
       
      Anything big I am missing here?  I am starting to believe that this chinese carb is the issue.  This quad came with the original carb, which I would like to rebuild and use, but the mixture screw is totally stuck, and stripped way down in its recess.  
       
      Thanks for any assistance.

      1989 Yamaha Moto 4 sputtering after new carb
      By jashadams
      Hey all back again with my 1989 moto 4 250.
      After putting a new carb on it it's really sputtery, it has new gas and I'm wondering what to tune on the carb to make it idle better. I've attached a video to describe the issue more. The bike is still work in progress but I think the video gets the point across. Thanks!

      Running engine without rear axle 2005 500 scrambler?
      By p5200
      I'm assuming, it's alright to test the engine after adjusting valves without the rear axle installed? Can someone please verify this? I'm waiting on axle parts and wanting to get that done while waiting. Thanks! 🙂
