Problems with starting 2005 yamaha 350 4x4 (wolverine)

[Nate Hanson]

I am a new atv owner...I bought a used atv this summer (pretty sure it is a wolverine but reg card from last owner didnt actually say that so idk for sure). It ran great for most the summer and early fall but one day I tried starting it and it turned over a while without starting and then suddenly it quit turning over at all. No click or anything.

I charged battery and light turns on showing neutral and heatlight can go on.

A few other things that may be pertinent: The pull start is missing, I have a fluke multimeter but not many other advanced tools (or relevant experience), there is an extra aftermarket led light attached to front but it doesnt work either... never looked into why since I didnt need it. 

I looked for a fuse box and didnt find one.

Please recommend some easier things to try first as I really want to avoid taking it in if I can (having one income and 4 kids can keep out extra cash, plus I want to learn). Pictures would be awesome if possible. Thanks!

Welcome to Quadcrazy @Nate Hanson First things first. Bottom left front frame rail should have a vin# stamped into the frame if its a Yamaha.  If you can locate that post the number here or look up any atv vin# identification web site and it will tell you what year and model. 
Now as far as the power problems go there are a few things you can check first.

1. Make sure the kill switch is properly working and not preventing the starter from coming on. Sometimes they get water inside or the contact breaks. 
2. Sometimes battery's have a bad cell inside and will have enough power to bring on the dash lights but not enough to crank so be sure the battery is fresh/charged/good.

More invasive stuff:

3. If your familiar with a tester you can put it on DC voltage setting and locate the wire on the starter and put the tester positive (Red) lead on the wire on the starter and the negative on a good ground or the negative terminal on the battery and push the start button and see if you get a reading.  

4. Under the seat or where the battery is you should find a relay with two larger wires on it. Both red in color, one comes from the positive side of the battery and the other goes to the starter.  Most of the time there is a fuse in the area under a rubber cap on the side of the relay so look for that fuse and check it.  This relay can also be bad and is not expensive at all to replace.   
On the relay the two red  wires i mentioned earlier that are bolted onto it can be jumped for a second and the starter should turn over.  But make sure the bike is in neutral and only jump them for a second or two.  You will see a few sparks and its ok but again if that starter does not spin then the starter may be bad.  
 

Start there and see what you get and check back in.
