Hi all, working on getting my electric start hooked up on my new 90′ fourtrax 300. Did some troubleshooting, was able to prove that I am indeed getting power to the starter. However the starter was showing no sign of life. So I went ahead and pulled the starter off earlier. Took the starter apart and noticed quite quickly that it was full of water and dirty gunk. No real debris in there just dirty watery.

Gave it all a good cleaning and tried to reassemble. Still no sign of life. I hook the starter up to a battery and still wouldn’t work. So for those that have some knowledge on these motors, is there a way to test the brushes and rotor to see if its good still? I understand the theory just haven’t rebuilt one before! Thanks for any input in advance.
