2001 Yamaha Warrior - No Spark

[Miked912]

I have a warrior that isn't getting any spark, starter turns over fine tho. Tried using a jump kit because the battery was junk and nothing, if it pull behind my truck I can get it to fire and run for a few min then it dies. It seems to run fine for those few minutes. I put a new spark plug in it and still nothing, can't see any wires that are bad. I tested the orange wire going to coil and no voltage to that. Fuse under seat is good Could it be the stator? Or CID box? Don't know how to test them and don't want to spend a ton of $ if I don't have to.

check out the SPEC page #4 for some specs with the pick up coil at the stator, you will need a voltage meter ,,, if you know a buddy with the same bike, you could switch up the cdi to rule that out ...

Hi and thanks for the welcome, I will check out that page. I already asked around and couldn't find anyone with same bike. It will now stay running after I jump it by pulling it, and if I hook jump pack up to it right after it will start but will only do that for a few min. Then nothin again. I have a meter so I will try that. Thanks for the help!

This is good timing for this thread. I have a 2001 warrior also. The battery in it was bad. After changing the battery I still couldn't get it to start. Like yours turn over, but not start. I have a new plug for it, but haven't gotten to work on it yet. The weather is holding me up, it has been single digits temp wise, way to cold to be doing any wrenching. I will fallow post for solutions and will post any progress I make. I am on vacation this week and will get into the garage soon.

more than likely it turns out to be the stator or pick up coil ... you can purchase the pick up coil separately from the stator, or the pick up coil is included with a new stator. it can be a gamble but sometimes works out saving money with just the pick up coil ...

if you take the side cover off where the stator is, (left side of bike sitting on it), you might be able to move the pick up coil closer to the staor and be able to clean the stator of oils where it is in contact with the pick up coil.

I had the same problem with the cold weather. I had taken cover off and cleaned it, tried pushing it to jump it again and it stayed running this time, rode it around for a bit shut it down then started it again off jump pack and it has worked since. I'm going to buy a new battery tomorrow. Maybe it was a loose wire or something but I'm gonna replace stator any way. I will let know how that works, thanks everyone for the help.

I am gonna get into the garage and work on mine today. I will get back with the results.

Got the plug out and it was fouled. Not going to try to start today, it is still only 28 degrees in my garage. Supposed to be warmer tomorrow.
