I know it sounds stupid but have you checked your battery ? Could be a dead cell that will show a little power. Also it could be your regulator/rectifier.  Take a tester when the bike is running and test the voltage at the battery during idle and rev it as well and see if it fluctuates on the tester.

Could be the starter relay, have you looked into all of the components of the electrical side of the bike. Check the relay and see what happens when you jump it. 
See if the engine cranks, there is also a neutral safety switch that you should look into as well. There are also other relays as well within the starting system so bottom line is your going to have to go part by part and check everything. If your not clear on how things work then feel free to ask.

      Hi guys, I have a 2004 big bear 400. Last winter while plowing the driveway, I heard a loud pop from the left side of the engine. It continued to run as I looked for leaky fluid, but then died shortly after backing it up and won’t start now. The oil light comes on when I try to start it, no noise or anything else. 
      No blown fuses that I can find.

      Hey guys and gals. I've been working on my friends 2007 big bear IRS. Unfortunately after 3 different people got their hands on it and only made things worse every time.  After months of finding just crazy problems everywhere. I'm finally at the point we're its almost 100% !!! But I'm getting a short somewhere between the 4xW switch I believe. I managed to by searching the internet like a  fiend, got my hands on an official Yamaha wire harness for the year and make. But I don't have the numbered component list and to be honest. After hours of going through and making everything so it's  easy to reference. If anyone has a picture of the referenced components. I would be forever in your debt. I've spent hours marking up the blown up diagram so it will be easy, for any possible future repairs. Please and thank you. Here's a picture of what i have so far.  Unsealed it in plastic so oil and crap won't spill or get smudged. This damn things worth it's weight in gold.              Thanks Jeff                2007 Yamaha big bear 400 IRS.       YFM40FBW
