Re: (ET) Motor weak and pulsing (Alltrax)

Sure. Power the motor with a 12 volt supply on field and armature. If it chugs it has a bad winding

Is there a way to test for this?  IIRC the armature has very low 
resistance to begin with.

 Sounds like the symptoms of a shorted armature.

 I have an E-15 with an Alltrax controller and BB-600 batteries.  All of a
 sudden the motor has become very weak and its output pulsates like the
 sound of a wheel with a flat spot.  It does this even in neutral, and when
 it's in gear it draws a lot of current (the current varies in the same
 rhythm).  Also the motor is quite hot.  Any ideas?
