Re: (ET) field rev.

Reversing the field and armature makes the motor run the same way.  It's 
the relationship of one to the other so only one is reversed.
On a compound motor, the speed regulation changes due to series field 
effect.

Reverse the polarity of all of your motor connections. See what that does. 
Please report back the results.

I'll do the same with my test motor this weekend to verify my suspected 
results if you would rather wait.
