I need a little diagnosing help. My '07 was running fine until I let my kids wash it the other day. After that, the starter won't engage. All I get is a killer buzzing from the relay under the seat. I haven't had time to trace anything yet, but I was hoping someone might have some insight as to what the likely problem is. Thankfully, I retro-fitted a pull start on it when I first bought it and it fires and runs like a top with that, but no more magic button! All other electrical components work fine, gauge, lights, etc. Any help would be greatly appreciated, thanks...SC
