I just bought a 1996 polaris 400 scrambler that was in pretty rough shape. I am now stuck on a problem with the electic start. When i push the electric start button - nothing happens(no clicks, no nothing). The starter turns when i hook it up to jump cables, i replaced the solenoid, and i charged the battery(2 years old). It starts fine with the pull cord. I looked at all the cables - they appeared to be alright. I cleaned all the connections off. What else could it be?
