Re: Fiero GE Series Motor Cabling

Series motors are reversible by nature, just swap
either the Field or Armature connections and turn the
Brush to advance them in the opposite direction. Done.

It's a standard series wound motor, right?  A1 A2 S1 S2?

Is there any reason it shouldn't be wired in the conventional way one
wires all series-wound motors... Jumper one of the A's to one of the
S's.  Connect B+ and B- to the remaining terminals.   Then swap S1 and
S2 if the motor runs the wrong direction.

And correct me if I'm wrong, if the motor doesn't have interpoles, it's
optimized to spin in one direction efficiently.  You had to get that
right at the time of physical installation.  You can't correct it by
swapping wires... right?
