2002 Yamaha Wolverine 350 No Spark

Recommended Posts

2002 Yamaha Wolverine 350

Does anyone know if a bad cdi box will cause no spark. I already replaced the coil.

It ran for just a second and now I have no spark again. Will a bad cdi box cause a

coil to go bad?

Any other ideas????

Thanks

Jeff

I have checked the wire to the coil. All lights work. It cranks just fine. Just no fire. You put the plug wire on the ground & no spark. Every light & switch works just fine.

Unfortunately it is still not clear because it could be the CDI or it could be your STator which I have also seen happen. May need to take it somewhere to be tested because eithe component is kind of pricey so you want to make sure you replace the right thing.

There is no way to check the cdi but by process of elimation. The spec ohm for the pick up coil is 170-220 ohms. The spec ohm for the chargeing coils is .70-.86 ohms. The spec ohm for the source coil is 270-330ohms. The spec ohm for the primary winding side of the ignition coil is .36-.48 ohms. The spec ohm for the secondary winding of the ignition coil is 5.44-7.36 K ohms. The spec ohm for spark plug cap is 10 K ohms. If all of these check out then your cdi is bad or there could be a wiring problem. Check for loose connections and bad grounds. Hope this helps.

      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. 😎

      Hi guys im new to the forum and i hope i put this in the right spot. But im putting this up for my uncle. But he has a 2002 Bombardier quest rotax 650 4x4 All wheel drive. Now i was driving it down the road today and all sudden it shut down i thought it ran out of gas but it didnt. After it shut downi pushed it to the side of the road and tried to crank it over but it wont crank over. It is a electric start none of the lights or anything work So what i was thinking its in the wiring somewhere right? Does any one have a website that has a wiring diagram for this 4 wheeler or does any one know what else it can be? If anyone has any idea please let me know everything willprobley help thanks guys!!!

      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 own a 2002 Can-Am Quest 650.
      It will start if you massage the throttle a bit and it will continue to run. BUT if you let go of the throttle and try to let it idle it will always die warm or cold.
      It has Non-Oxy premium gas, a new gapped NGK plug, a new carb (as of today) and fresh fluids. After installing the new carb it runs exactly the same.
       
      I only have a few things that I have observed since the new carb:
      The choke still doesn't do anything. It has a good cable and it is hooked up. It on fully off. There is a cable in the top, front of the engine that splits into two connectors. The connected side is in the photo. The other side has the yellow banded section and is not connected. I do not see anything in range of this connector so I don't know if this is normal or not??? The original carb wasn't really dirty or clogged. I'll use it as a spare. I don't see this cable and connectors listed in the Can-Am shop manual. Looking for some help. I want to ride!
