Well my 1993 Yamaha just suddenly stoped working, Iv norrowed it down to be a loose wire (I'll check tomorrow) or the starter but Im leaning more to the starter. A guy I know has a big bear motor with a good starter in it. My question is will the big bear work in my warrior?

If you have the time could you please help be with this if you have a second to read
My warriors electric start recently stoped working. I was out for a drive and it wouldn't start up again after I shut it off, I moved the bike around and tryed again and it started right up so I went home because I didn't want to get stuck out in thw woods with it. When I got home I put it away and the next day I tryed to start it up and it wouldn't do anything. I moved anround the syleniod a bit and I could hear the starter try to turn the motor over, it made some weird sounds but didn't seem to have the power to start the bike. Is this A)The sylenoid B)loose wire C) the starter

Thanks

 

anyone???
