My Sportsman has been mothballed for a while. It was outside, covered but cover and tarp got ripped some how. Put in a new battery only to find that the solenoid was defective. Changed solenoid but still no power going to instrument lights or else where. I took starter wire off solenoid and with key on, touched wire to battery terminal. Engine turns over but there is an initial spark and nothing else. I took off recoil case to find moisture, not dampness, actually water inside case with lots of rust. Could my stator be done, or could there be another issue. Can I take the flywheel off, clean everything and possibly fix my problem? Any help would be appreciated. thanks for your time.
