Need help 2008 Yamaha Big Bear 250

So what if its the ignition switch instead of the starter? Since it cranks couldnt the lead in a different direction now?

Ok thats fine but at least the starter is working.  That small plug on the relay, one wore should have 12v to it. If you have that then the solenoid is probably bad.  Easy enough part to get.  Double check your kill switch is also working properly and not causing all this. 
I would also pull the spark plug out and test for spark while your cranking the engine. If you have no spark and no start button then the problem could be causing them both and not a bad relay.

Start button does absolutely nothing. No click when I push it. Spark plug is new and gapped according to specs for the Bear. I can get another solenoid for it and it be here in a couple of days. Thats cheap ebough to replace

Check the (white?) 12V output wire of the solenoid that goes to the ign switch, make sure it has power. I had a Kawasaki a bit ago that wasn't providing output voltage even though the solenoid itself was ok.  Also, have you checked continuity in the ignition switch to make sure it's good?  there's only 4 poles usually; 12V in, 12V out, and the other two are just a circuit that closes to interrupt the CDI to kill the motor when you turn the switch off.  Have you checked continuity on the start button to make sure it's making contact when depressed? 

I think you almost have it licked, just one more little issue here to trace down.

Agreed with @MarkinAR on all things to check. Im sure the spark plug is fine, new and gapped etc. Not what I was getting at so pull the plug and test for spark while your cranking! Reason why: All though your solenoid may  be bad it would not prevent the engine from starting by jumping the solenoid. So if you have NO spark then like i said earlier,,,the problem may be something causing the solenoid not to work as well as KILLING the spark. Get it now? For instance if the kill switch contacts inside the switch broke it  will not allow the atv to start.  This is a common problem, including instances where the insides of the controls being soaking wet.   Wire harnesses short out from the outer insulation wearing away From rubbing against the frame etc and eventually short out against the frame.   So you should be wiggling the harness and pressing the start button to see if there is a short or a break.  There is also a fuse next to some of the solenoids under a rubber cap.  
There is a process of elimination here that you should follow and the problem will surface.  Feel free to order a new solenoid but it may not be the issue and days wasted.

Its been a bit since Ive posted. Had to wait for parts. In the past couple of days, I  replaced the ignition button and got a low click at solenoid. Replaced solenoid, got loud click and then replaced battery today. It still wont start. What next?

So it's turning over just fine with the start button.  Now you have to move on and see if the spark plug actually fires a spark (or put a screwdriver in the plug boot instead of the plug and see if it will fire against the head), then on to fuel, etc.

      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!

      First time using this forum.  Owned a Kawasaki dirt bike once, had no issues.  But I picked up this 4 wheeler at an auction.  They stated it ran, but only needed a battery.  Well I do not believe that was all true.

      Some pictures are attached.  Not sure why, but the whole air filter stuff was removed.  They had some small thing inserted as a make shift air filter.

      I purchased a battery to try this all out.  Waiting to return it and get the proper size, as it was too big for the battery box.  But here is my issue I had while the battery was connected.

      1 - The lights on the steering column did not come on.  Not sure if they work or not.

      2 - The starter solenoid seems to be bad.  I have a new one on order. 

      3 - In the pick, there is another rusted part.  Not sure what that part is or what it is used for.

      4 - What is the 12v rectifier?  square bodied part.

      So when I hooked the battery up.  Pushing the start button did nothing.  Pulling the cord to try and pull start, it turned, but would never fire.  I have put in a new spark plug as well, it looked worn out.  With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.

      I have read a few other threads and it stated something about needed the neutral light on.  SOmething about a kill switch.

      Any help would be appreciated.

      I have an older (1987) Yamaha Big Bear 350.  I have arthritis in my thumbs.  Is it possible to replace the accelerator with a motorcycle accelerator (ie. twisting the handgrip)?  This would be more comfortable for me due to the arthritis.
