2000 Yamaha Warrior - No Spark

Recommended Posts

My sons 2000 yamaha warrior will not start. It will turn over but not fire. There is no spark @ the Spark plug. I can pull it off and it runs great. I tested the stator and the ohms were very low on one of the plugs. should i test anything else?? and if so how??? (i will apoloize in advance...i may not know the proper names of some parts..I have never done anything like this....I'm just a mom trying to fix sons bike...if i can. :frown:

I changed spark plug. Made sure wires going to spark plug had good connection. Tested the ohms from the wires coming from stator. One read 291 and the other much much lower, although i can't remember the exact #. sorry. I should have given you more info. hope this is better and thank you so much.

I don't have a manual for the warrior, but You may want to test the coil, (what the spark plug wire connects to). Even a bad plug boot can cause this.

Blaster/raptor/warrior/banshee- remove the plug boot by unscrewing it- check the resistance of the boot by; putting one end on the screw and the other where it plugs on the sparkplug should be between 4-6K Ω, if that checks ok next- the primary resistance of ignition coil [positive lead (red) to the skinny power wire coming out of coil unplug it to test this-to generator(stator) and negative lead (black) to one of the grounding terminal on either side of the coil] should get- 1.44-1.76Ω Secondary resistance [positive lead (red) to the plug wire and neg (black) to the power wire on coil to generator(stator) again unplugged] 5.28-7.92K Ω.

If any are not in this limit replace it! Hope this makes sense to ya!

Thanks for all the info and help. This stuff is driving me crazy. Can the stator have a very low ohms reading and still be good?

ok, stator is good because it runs when pull started.

cdi box is good because it runs fine.

voltage regulator is probably fine too.

coil is good because it runs fine when pull started.

how fast does the motor spin when trying to start with the electric start?

if it isn't fast enough, it won't produce a healthy enough spark .

it could be the battery or the starter, or both.

also, what i would do is strip as much plastic away so you can check all your wiring. there could be a bare wire(s) touching the frame. check everywhere the wiring is tie strapped on and where there are wear/rub marks regardless if it is encased in a protective plastic. peel it away and look and you can always tape it back up. you could also have someone help you to see if there are flashes in a dark garage or outside while cranking it over with the starter motor.

Thanks OB. I did try to jump it off with no luck. I pulled it with the tractor and it did start but I had to pull it pretty fast. I was then able to ride and it sounded great. I replaced the starter about a yr ago. Don't no if that matters or not???

Should I check all of the electric wiring? Am I just looking for damaged wires under the insulation sheath?

i would check everything that looks worn, even unplug the connections and look inside for corrosion and repack the connectors with dielectric grease.

Got it. So, if it runs after being pulled off then the stator is good? Thanks for all your help. I hope to understand this all of this someday. I hope I don't question u to death.

:yes: we are all here to ride and have fun and help each other out, and you're not questioning me to death :no:

i think something is interupting the path of the electric starter, the bike runs fine with it being pull started, so i would have to think there is a wire(s) grounding or a bad starter or battery....

OX..... that was a freaken cool pic!! you can just buy that part and change it??? and about what can you expect to pay for one?

i'm pretty sure you can buy separate ... i know both stator and pick up comes complete new.

check here Ricky Stator - Manufacturer of ATV & Dirt Bike Stators, Electrical Components, Lighting Systems and Suspension Products and you can email them here [email protected]

or you can try a yamaha dealer too. not sure what they are worth, $50 or under i'm sure

The screws that hold the pick up coil in are really tight and I don't want to stripe them. Any advise. Sorry fpr type

o'S I am using phone with gloves on. Didn't want u to think I was completely stupid. Ha

mine were in tight too, sometimes if you give them just a little tightening, just to move it ever so much, it breaks it free. then you can back them out. you can also try keeping the screwdriver in the slot, and tap it with a hammer...

      Question: Do you have to take gas tank off to get carburetor off the quad. ?? 
      It's gummed up again and needs cleaning. Put Sea foam in tank hoping it would dissolve any crud. No joy

      Hi, I'm a new member
      Just bought a used 08 350 raptor with about 5 hours on it ( very clean ). Started fine when we got it. Now after a few mods (bumper, skid plates, air filter) Now will not start unless you pull in the clutch. I've checked just about everything and also checked that there is no pinched wires. Anybody have any ideas?:bangheadc: Thanks, Dave

      Have an Bear Tracker 250. Dont have the manual or any literature to help with. Anyhow, starts with pull start in gear, and electric starter doesnt work. Also, neutral light doesnt come on. Where should I begin?? Need some direction on troubleshooting all this. Thanks a million.

      Hey everyone, I've been scratching my head over this for most of the day.  I bought a couple of Bayou 220's, got them running (they've both been sitting), and started tweaking and fixing small things.  One of them is mostly done, the other had an aftermarket carb on it and I've been trying to sort that out.
       
      Anyway, while adjusting the carb it died a few times, I restarted and moved on until it died and wouldn't restart.  I figured maybe I'd flooded it or something - after further attempts I realized I had no spark.  Since I have two identical machines I have many parts at my disposal.  I've swapped the CDI, spark plug and coil with no luck.  I have good resistance readings from the stator and pick up (135 and 110 respectively),  I don't have a peak voltage meter but I measure around 53VAC on the stator when cranking.  I have a 4 wire stator, not an alternator like the newer ones.  Grounds look good, I've checked the kill switch by verifying that it and the ignition switch grounds the black/yellow wire to the CDI.  I can turn the engine slowly and see the pickup short the meter as well, seems normal right?  So far everything I've checked looks the same on both machines.  I've got the service manual and wiring diagrams.  Do these readings make any sense?  I'm obviously missing something but I'm stumped.  thanks!

      Hey all new member so I'm sorry if this isn't the correct place to post, but I'm having trouble with a 2000 polaris magnum 500 I just acquired. The quad ran when I got it but was having problems that sounded like the camshaft, and sure enough camshaft lobe was pretty much gone, so we replaced the camshaft and exhaust rockers and now the quad doesnt have spark. We had the quad running right before we tore the old camshaft out and now no spark. Anybody else ever have a problem similar? We've been checking for loose wires, checked grounds, and double checked timing but cant get it figured out so any advice would be appreciated! Thanks

      I have a 91 big bear 350 4x4 with no spark what's making me puzzled is my coil is up to spec with ohms my stator and pick up coil is up to spec brand new and ohms reading checks out I got power from CDI coming out and power going in my coil wire from coil to CDI is getting good ohms reading plug is brand new but still not getting spark any suggestions or help would be appreciated I'm getting confused where do I go next please help me thanks

      Trying to help a friend with his 2004 Yamaha warrior 350... It wasn’t getting a spark so we replaced the spark plug, cdi box and coil. Have tested the kill switch, checked fuse,  everything is good there. Monday (8-20-18) we installed a new stator and got spark, ran it around my trails for about half hour then put it up. Today (8-25-18) we went to go riding and it wouldn’t start, again getting no spark... can’t wrap our heads around what happened when we got spark back then a few days later nothing... any help would be greatly appreciated

      Hello. I'm new so I hope I'm posting in the right place. My neighbor gave me a nice looking Bayou 220, but I can't get any fire to the plug. No lights, nothing. So far I've put in a brand new battery and relay. So those are good for sure. No neutral light comes on when the key is turned. Where should I start to try to figure out this electrical problem? I have a new coil to install, but common sense tells me it has to be something before that. I'm cheap so taking it to the dealer is out of the question. Does anyone know the process of elimination in a situation like this? I'd might add it LOOKS like the wires are all where they belong, but I can't say they are for sure. If the machine wasn't in such great shape, I wouldn't bother, but the grandkids should have a lot of fun on this. Thank you in advance for any help someone can offer.
