Hi guys, I'm new here and I have a question about an 2004, 450 Foreman that I just picked up. It has about 1000 miles on it and everything was running fine for a while, now the green light that indicates 2 wheel or 4 wheel drive is blinking and it will not go into 4 wheel drive sometimes. I don't have a manual yet and was wondering if you guys could give me some things to check? Thanks
