81 class engines do not shunt the field. The Traction motors are in
Parallel with each other. As was mentioned by someone else but ignored
by most the Load meter reads the traction current to one traction
motor therefore times load meter readings by 6.
Max. continuos Voltage in my Manual is quoted at 1300 volts and max.
continuos Amperage is 7020 Amps. Rated Power is 2237 kw.

By the way G and BL's are also Parallel Engines as 82 and 90 class.
