Hello, my wife has received a John Deere 330 with a Yanmar diesel that was her grandfather's. It has been sitting a long time, but I have serviced it and it is running. When we got it the rectifier was fried (along with the wiring to the alternator.) I have replaced them but it still isn't charging right. Any ideas,? Anyone have the correct wiring diagram for the rectifier? Any help would be great! Thanks!

Testing Alternator Output(Unregulated). This is measured in AC Voltage.
