Dewalt 744 Portable Table Saw
Previous owner replaced the armature, field and brushes in the motor in this Dewalt 744 Portable Saw but it would not work.
I have voltage all the way to the brushes.
I disassembled and found nothing unusual.
I tested the armature and field and both are not shorted or open.
My next focus is the field orientation.
It appears the field can be installed-"either end first".
Is there one correct orientation to install the field?
What else can I check before reassembly?
Thank You for your help and comments.

Dewalt 744 Motor REPAIRED
Well the mystery is solved and the motor runs.
Going back together, I had voltage up to the point of clipping in the Brush Housing.
Peeking inside, one of the mail spades on one of the Brush Housing did not go into the female fitting, but rather "slipped off" to the side without making contact even though the Housing clipped fully into place.
When I pulled out the brush housing the spade "sprang back" and you could not tell by inspection that it was bent. Probably happened when they installed the new Brush Housings and I repeated it during my first reassembly.
Thanks to all who looked at the post with the thought of offering help or learning something. I learned some valuable lessons about Root Causes.........School is now out of session! Back to the To Do List.
This is a great site, I'll be back.
