Completely new to motor work or any kind. I have started a project when my winch died on my ATV. I have stripped it all down. I had a broken brush , which I made a new one, there was some rust on the armature and the stator, cleaned it up with a light brass brush and contact cleaner. I have tested the comutator with a multi meter and it seems like it's all okay. Putting the motor back together and hooking it up to the solenoid, it will rotate the shaft for half a second or so, a couple revolutions and then stop , it will then do the same in the opposite direction but wont stay running. Any ideas?
Have you measured the resistance through the armature statically for all positions of the rotor?
Its not uncommon to burnt out a winding or two on an armature of a DC motor.

Winch motors are like starter motors in that the brushes carry a large current. Did you make the new brush just like the existing brush? Both should have embedded copper braid to carry the current. A simple brush holder won't work.
