AC620 0 Posted July 25, 2015 Had a new starter put on our AC 620 and the shop had issues. Lack of knowledge/skills had to do other repairs afterward. Since this work was done the battery will not charge. Lucky they got the starter working on the 3rd try. Does anyone have the schematic for this tractors electrical systems - imparticular the charging system?? My e-mail is john651@roadrunner.com... Thanks for the reply.
