What company manufactured Master Mechanic generators and how do you obtain wiring diagrams for them?

I would love to get my hands on some wiring diagrams also. My unit was made by;

Master Mechanic Manufacturing Co.

Everlite Division

Burlington, Wisconsin

I have a model FSRE? ESBF? It's hard to tell. letters are not stamped very deep on the tag. It is powered by a B&S engine.

2800 watts

S/N 73B(R?)

Hope this helps.
