No battery charge from 24 V alternater

My alternator stopped charging the battery. It looks like alternator is OK. I measured voltage on black and red wires comming from the alternator at 25v at 750 engine RPM. At low RPM the alternator red light is no longer on. Is there a schematics or wiring diagram for 24 v alternator, and regulator?
Please advise troubleshooting steps.
