Too bad you are so far away....

The main speed control is a sequential switch; farther forward is faster,
reverse direction is the same way. The E-10M, E12M, E12 are 3 electronic
speeds forward, 2 reverse. The E14 (not GE branded), E15, E16 (not GE
branded) are 7 speeds forward and 3 reverse (as I recall), all by hand
control. The E-20 as I recall is 20 speeds forward and 7 reverse, all by
foot control (similar to the control on most hydrostatic transmissions).
The switches control relays, which control motor winding combinations. It
is really just relay logic. PWM speed control through motor current has
been made by at least one member of this forum, but was not at all
