400 HZ MG set

[roger]

Does anybody have schematics for a Westinghouse 75KVA 120/208 V 400HZ MG set or know where to get them.

The unit is probably 30 years old and was running on Thursday at 480 volts. It was moved to another state on Friday and reconnected on Saturday at 240V delta. (voltage was changed on motor and control transformer) Motor runs fine but cannot generate voltage. There are some PC boards in the unit with one point connected directly to the #7 lead from motor. Obviously this has changed the voltage on this conductor but not sure what it does. (I think it has something to do with the DC excitation conversion)

Thanks

Roger

I have an overseas customer who is looking for on-site field service for approx 10 (MEP 115A) and 10 (MEP112)....These are pretty old generators. They want to make sure that the contractor has the ability to find the parts needed for these gens as they they are uncovered.

If anybody has suggestion please let me know.
