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

      Got my Yamaha Grizzly buttoned up finally and went for a quick 2 hour ride in the power lines with my neighbor, who has a Yamaha Kodiak. We have access from his yard, which is nice. Was a beautiful day today to get out and will try to go more often. Ran into two other quad riders with a sportsman and I think grizzly. Also ran into a dirt bike rider. 😎

      My father-in-law gave my boy a 1999 350 Big Bear. It's been sitting in a barn for a bunch of years. It runs great! My boy has been riding a couple weeks now and it has developed a squeal coming from the front end when you get off the gas at speed. No noise during acceleration. At first I thought brakes. I took it for a ride and I don't think it is the brakes. I feel it is the front prop shaft U-joints, front differential or one/both axles. I pulled the fill plug on the differential and I can't find anywhere how much gear oil should be in there. My gut says up to the fill opening. It doesn't have a manual. It's wet in there, just don't see any gear oil.

      #1 Should I fill the differential with gear oil up to the fill opening?

      #2 How do I check or know if the u-joints are bad? That looks like a "Big Bear" of a job if they don't need to be replaced.

      #3 What else could it be? I don't think it is the front bearings. I jacked the front wheels off ground and no play in the right wheel. Very little play in the left wheel, looks like the lower control bushing is where that play is coming from. The rubber CV boots look original but all still intact. Wheels spin easily without any noise.

      Thanks for any help!

      I have a 2000 Honda trx90 I got from a buddy for free he said it needed a carb so I put his old carb back on it to try to get something out of it and it does not have any Spark. I already replaced the ignition coil I don't know much about four wheelers but I am a technician so I do know my way around a motor any electrical help would be wonderful or specs I don't have the best digital multimeter either.

      Hey y'all. I have a Yamaha ymf 250 BearTracker. I got this thing for free from people whose son tore it to hell. So it wasn't in great shape to begin with. i.e. no indicator lights (neutral light for instance), no ignition switch or key( wires were twisted together to make it run), get the picture yet? 
      So when it ran it ran rough and I got it running for a year or two, just something fun for the kids to ride on with me on gravels.
      Now just randomly, the start button stopped working so I had to jump the solenoid, then put a temp start switch in. Kill switch would still work. 
      However, the thing has no spark what-so-ever. I've check continuity through the start button and it shows the contact is working, ohmed out the stator, everything is in spec, the reg/rec tested fine as well. I've replaced the solenoid on the off chance it could've been bad and the cdi unit as well, along the the little solenoid relay unit. I'm still getting no spark. The spark plugs is new as well and the coils to the plug have been tested and are good. I've tested and trouble shooted everything I can on this quad and no luck. I watched countless YouTube "no spark" situation videos and it's not helped. Does anyone have any tips or tricks I could try? Would really appreciate some input on this. Thanks!

      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
