2000 Yamaha big bear 400 won’t start

[Mister907]

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.

Well, I think not even 5 mins after I posted that, I got it running. I never use the “kill switch” on the machine. I always turn all my machine off using the key to avoid draining the battery if I did forget. So guess what the problem was? That’s right, the kill switch was in the off position. Ugh, I feel so dumb. Lol.
