Re: (ET) E12-S stopped running

Sounds like very high current draw.  I don't remember now, is the E12S 
motor 
a wound field or PM type?  If the former, you may have little or no field. 
 
Check for battery voltage at the field terminals (fastons, IIRC) on the 
motor.  Disconnect one armature connection before performing this 
measurement, or you may damage the motor.  Trying to run without field can 
overheat it.

If it's a PM motor, the magnets might have become demagnetized from 
overheating.  Or a bearing could be partly or fully seized.
