Okay, I don't think I'm understanding you correctly in regards to "field winding". That is not the same as the armature winding, is it?
Here's what I did:
Note the red wire (jumper) that grounds to the frame.
And the gator clipped to the other brush for illustrative purposes.
(During testing, I didn't clip it, I just touched it to the brush holder.)
The above resulted in the armature vibrating back/forth. No rotation. I would only touch the lead to the brush momentarily, for I'm sure I'm not connecting it correctly.
I don't think I'm understanding the "field winding", nor am I understanding where to find it so as to jump it to one of the brushes.
I downloaded the first page of the above links and have read it. Reading the info, and looking at the other schematic supplied that's on the first page, I now ask:
Is the "field winding" the coil that sits on the outside of the motor toward the back? i.e. The tab with wire soldered to it indicated by the yellow arrow below:
I'm certainly learning... but I don't seem to be very good at it just yet!.
