I have a 2011 Case 590 Super N that's not charging, anybody have a wiring diagram for it by chance ? It has a 120A Iskra alternator on it that has what appears to me to be an external voltage regulator on it. It has a 3 wire plug connected to it that has a 12V hot (to the center terminal of the plug) with the key turned on ignition. The 2 end terminals have neither power or ground. The heavy wire (high current charging) has battery voltage to it and the alternator case is grounded as it should be. I'm guessing its a bad alternator but I hate to guess till I ruled out a wiring issue to what I'm thinking is a external voltageregulator. I included 3 pics - Thanks in advance for anybody's help.
