ok i picked up the welder from skid steer steve but am having problems with the starter engaging (as what he said in the description). its a engine driven 225 if u didnt read the post and made before 1973 with a onan engine. ive checked out most of the wiring and redone some along with replacing a bad starter solinoid. i havent been able to get anything out of the starter so had to pull apart the generator case and as far as i know from the past doubles as the sarter and am going to try to clean the shaft but am stumpted . ive had my brother help me with checking the shaft which i dont know the proper name to and seems to not be shorted. does anyone know of a lincoln message board i could ask about this on or a wiring diagram its model # is 5574. sorry for the long post any help is appreciated
