Operation and service manual 37.5 KVA military Diesel Gen set

[billgkc]

I’m in need of a operation and service manual. This is what I know, this gen set was built in the 6o’s by John R. Hallingsworth, the name plate has this… Federal Aviation Agency Contract #FA-WA-4219 Ser no. 30-878-63 John R. Hallingsworth Co.

I have a schematic that appears to match with this model No. JHDW37.5C 37.5 KVA 120/220 volt 60 cycles 3 phase

I need a operation and service manual. Also I have ran it for a short time and sparks are coming out of the flywheel and engine running at high RPM with no load. Any Ideas would be apreciated.

Thanks, Bill
