I have a 2004 Polaris 600 sportsman twin and am having electrical problems. I just put a new battery in last week and took it to the mountains this weekend. It ran fine on short rides but when I took it for an extended ride up some steep terrain something on the right side of the motor started to make a lot of weird noise. After a few more miles I slowly lost power to the point where it stopped running. I had to jump start it to get it going again to get back to camp. After it cooled down the next day it started with no problem. Is there something behind the cover on the right side that acts as an alternator that could be going out that made the noise and caused the problem?
