Craftsman 137.218250 10 table saw. Stopped while cutting hardwood

This answer was rated:

CraftsmanNNN-NN-NNNN10" table saw. Stopped while cutting hardwood (IPE). Now won't start. Is there a reset button?
Does the motor make any sound at all when turned on to run? If it 'hums' or buzzes let me know. If not we may have to do some checking with a meter, is this something you can do with my help?

No motor sound when turned on. I have a multimeter,
first I want you to open the brush holders and check the brushes, There are two small round black cap on the motor, one on either side of the motor for two brushes. Unscrew that cover and check that the brush is there and at least 1/2" long. Tell me what you see and if the brush is OK

the "brushes" look like two spring-loaded metal blocks. Each is a little longer than 5/8 inch in length. I took them out, cleaned the sawdust out and put them back in. Still won't turn on.
Roll a thin piece of light grade sand paper and slip it in the brush holder (with the brush out). Spin the motor by hand and clean the armature with the sand paper. Give the brush face a lick too! Then install brush. Do both sides.

Tried the sandpaper. Still nothing.
Ok, time for the meter tests. Put your meter on ohms scale. Put leads to plug end feeding the saw hot and neutral prongs on the cord. While on plug, turn switch to 'ON'. If switch is good, should see very low ohms, maybe 1-2 ohms into motor. If nothing or open, get into the switch and check the switch connections and ohm though the switch terminals to the wire in wire out terminals.
