Re: (ET) Motor trouble




Disconnect one of the large wires, carefull not to let the stud turn 
inside the motor. Mesure between the two large armateure studs with a ohm 
meter (old school Simson 260 would be great). You should see a low 
resitance. Turn the motor shaft by hand you should not see any opens as 
you rotate the armature.

But you don't know that until AFTER you get it apart. :)
