A friend who I ride with has an '03 Ozark 250 that won't always push button start. When you push the button, nothing happens. It'll pull start fine, and runs fine, and typically after it's been running for a few minutes he can shut it off and it'll start up fine. Not always, but sometimes.

Sounds a bit like a short or a bad battery doesn't it? Any suggestions on where to look or what to look for? I'm used to working on my Honda, and have pretty much got all the kinks on it down, but I'm still new to working on ATVs, and have never touched a Suzuki.
