My dad gave me his 1997 Polaris 400 express 4wheeler, he keeps it in his shed, took it to the shop because it wouldnt start, said that there was water in the starter, took it home ran fine for about a week, same symptoms no start took it back to the shop, they said water in the starter again, they asked if I had left it in the rain or gone through a creek or mudhole, I said no it sits in a shed closed up where could this water come from? the radiator? anyone had this problem, please help, cant figure this one out.
