its probably the brushes inside. if it were the bendix, it should have still wound up when given power. and giving a direct feed of power from the battery to the starter should have made the starter turn over regardless of any other issues.
i would either go OEM of ebay or get a new brush kit installed. if you go used off of OEM, you dont have any idea the condition of the starter. you should be able to get a brush kit from polaris for about $70 and it would be about an hour for a shop to install it, or you can try to do it yourself. i know when we rebuilt starters at the shop, it would tend to be around $150 total for labor and brush kit. just another route to think about
