2016 Yamaha Kodiak starter issues advice please


Guy Churchward

Recommended Posts

I have a 2016 Yamaha Kodiak and find myself with a start issue.. I changed the battery so it’s not that.. here’s a video of me trying and then boost starting.. can anyone give me pointers as to a starter motor issue or fuse or wiring or whatever ?.. I find myself without a vehicle with a tow hitch for the 1st time in years so have a dead and stranded ATV to fix !

thanks in advance, suggestions welcome

Guy

Hey guy welcome to Quadcrazy. 

Do you hear the solenoid click when you press the start button? If so great, take a tester or test light and put it on the wire on the starter that's covered with a small rubber boot and press the start button, if you get 12V then its a bad starter or brushes  

If you get no click then do the following:

Pop the seat off you will see the red wire coming from the battery to a starter relay/solenoid.  The solenoid has two wires bolted on it, one from the battery and the other goes to the starter.  There is a small fuse next to this solenoid in a rubber cover that holds the solenoid. Check that fuse first and see what you find. 
 

 You can jump the two wires together for a second ONLY A SECOND and you should get a little spark and the engine should crank. If it does not then its one of two things most likely.
A: starter is bad         B: starter brushes are bad. Both inexpensive to replace. My guess would be brushes. 

Before you start taking things apart first loosen and retighten the wires on the starter and the relay and check all grounds.

@Guy Churchward I downloaded the video you attached and it looks like you are getting it to crank, but its weak. You then got it started at the end of the video. What I don't understand is that if you changed the battery, why did you need to jump start it? Is that a booster pack you are using? Was the battery fully charged?

Looks to me like its not enough battery/booster power to the starter or a bad starter the way it sounds when its cranking.

Agreed! I was just able to download as well. I am now able to open videos that i could not  before on my phone! Sweet!!  
So it could be a sluggish starter.  I don't want to throw any major suggestions out there  but the decompression/compression release could be having a problem.  
Go the simple route first and make sure you didn't get a skunk battery. Maybe a dead cell inside from the factory, it happens.  Check all wire connections like i mentioned earlier so you can eliminate any of that.

Thanks to both of you.. I had the issue on an older battery and changed it.. if I fully charge the battery is has a chance to turn over.. however, most times I have to boost it to turn it over... I assume it’s a simple fix but am not a bike guy and don’t want to go changing things and hope.. will investigate based on the above and see what I turn up in the next couple of days.. thanks for the response

Ok frank and ajmboy... I just tried a direct wire across the relay nuts and got spark and no crank ... So does this mean a knackered relay or a knackered starter ? - I checked the 2 fuses and they seem fine btw... also wires up top (haven’t pulled the side off... see all tight ?

 

pic of what I jumped across, bloody thing was trying to spot weld my wire as you can see from the scorch marks ! 
 

thanks in advance for the help !

You can only do that jump for a second. Otherwise you will get the marks and possibly weld the wires to the nuts.  
But heres the thing, before all that pull the battery and run it to the local auto store and have them do a load test on it.  Its free and will tell you if its good or not. 
 

But for now try this.  Pull the spark plug and see how it cranks.

Ahhhhh ok i didn't realize you changed the battery.   So yes see how it cranks without the spark plug.  It really can only be a few things. The starer and or brushes inside of the starter.  Or the decompression weights inside the top of the cylinder head on the cam.  Sometimes the small springs on the cam weights come off. But go the starter route first. You can pull the starter off and bench test it also if your handy.   

If you pull the spark plug out and it still had trouble cranking then it's definitely the starter.

I would go the simplest route first and change the starter.  I hate to say that because i like to verify what the problem is so your not wasting money but its hard to say at this point.   
Im assuming there is no pull or kick start to try and see how hard the engine to start that way ? 
Just a though but did you do anything to the atv before this happened like oil change or anything else ? The oil level is proper and not over filled ?

No changes t all, hardly used, just for transporting trash cans up and down a private road so no dirt or swamp or water etc etc... the batter on load showed an issue but the shop were pissy on changing it under warranty (<12 months) so they wanted to keep it at the sho- and run tests.. suspect that was code for ‘we will inconvenience you and see if you just fold and buy a new battery !).

would you still change the starter as well or wait for the verdict on the battery ?

      Hi everyone. 
      Let me explain the thread title. 
      My husband and I are very active in the nudist community, and we have stayed at many and most of the mainstream nudist and clothing optional campgrounds in the USA. We are now approaching our retirement and would like to start a podcast to share those off the road / backwoods / little known camping areas where nudity is allowed. We have purchased a 5th wheel camping trailer with a rear garage for the ATV and now need some good reports on the one to buy. 
      We are most interested in a side by side unit but would love to get your thoughts. 
      Feel free to stop by and say Hi and ask anything you would like to better understand what we are looking for in an offroad unit. 
      Thanks for reading and hope to hear from you.

      Hello everyone, I just picked up an 02 LT-F250F the other day and have been in the process of tearing it down to fix some stuff- one of which was the cylinder base gasket leaking like a sieve. Well, I know why that is now, and I also discovered that someone had been in there before. I didn't take pictures, but it looks like it was probably run low on oil at some point, the cam journals and the "bearings" (for lack of a better term) in the head and the valve cover are totally wiped out, very deep grooves.  From what I know it's very difficult to repair aluminum in this way, so I'm trying to figure out where to go next.
       
      1. Have someone grind down the head and valve cover and fit actual bearings in since the aluminum is screwed, and have the cam ground down to match.  I have no idea what this would cost.
      2. Buy a replacement head+cam+valve cover.
       
      #1 I was hoping someone might have some advice on, but #2 seems like it'll (probably) be the more cost effective option.  However I'm running into some difficulty, it seems like the 2001 and 2002 models specifically use a different head part number,  11100-19B10, instead of  11100-19B01 like for all earlier models.  What exactly is the difference between them? There are obviously far more of the earlier heads because it ran for over 10 years.  Are they actually interchangeable? I've also noticed there are heads from the LT250EF that has 4 valve heads but also otherwise look identical.  Would those work as well possibly?  I'd like to not have to drop $500 on machine work or new heads on a $1300 quad that I'm already putting a bunch of new parts on.  Oh, and it has a new piston and the cylinder itself looks pretty good too, as I said someone was in here before me.
       
      Any help or advice would be greatly appreciated. I'll post pics of the carnage tomorrow.

      I’m looking for a top end kit for a Yamaha. I would like to see how well the engine runs before spending $6-$7 hundred on oem. Niche has complete kits from $1-$2 hundred.  Anyone have experience with Niche or similar Chinese companies?

      Bucking started about a month ago and works ok after 1/2 hour warmup.  Today while working on it i discovered that if i put the ignition switch in LIGHT position it runs fine right from the start.
      I'm stumped!  Any idea why this could be?

      Hey all,
      I need some input on a problem I'm having with my Kodiak 400 that keeps fouling plugs. First off, I've done a lot of work to this thing, most of it all in good fun. Brake work, cv joints, u joints, carb kit, checked valve lash, compression good, changed all fluids, etc... My problem is it keeps fouling plugs very quickly. I can put a new (manual recommended plug) in and it starts right up, runs great, idles great, picks up good. Doesn't stutter at all. I ride it for 1/2 a mile, it cuts off and won't start back up. I let it sit overnight thinking maybe it got to hot. Try to start it the next day, nothing. Put a new plug in, fires right up, runs great for another 1/2 mile or so, dead. The plugs come out and look carbon fouled with dry black soot on them. I don't know if this is a fuel/air mixture problem or a ignition problem. A couple of things that I noticed is I never need to pull the choke out to start it. Also, when it starts it automatically idles high like an automatic choke would do, then it comes back down to a good idle. Also I noticed that the air/fuel mixture needle valve screw does nothing when I adjust it in or out. I can screw it all the way closed and the motor still runs and idles good. Any advice would be greatly appreciated. I'm almost leaning to a ignition breaking down the plugs??
      Thanks!
