Onan starter motor problems and fix:
Main culprit is oil dripping onto and clogging up the starter mechanism
If there is any oil dripping from the Onan, investigate the source and correct it.
My main problem was the oil filter mounting bracket loosening from vibration and dripping oil onto the starter motor.
New gasket and locktite fixed that problem from recurring after the starter was disassembled and cleaned.
Also had the oil pressure switch develop a leak not from the tapered pipe threads but from the housing itself.
