This coil may be cut out by disconnectingits ends x, y, fastening them back out of the way, and con-necting bars c, d by means of a small piece of wire orjumper e, as shown in Fig. 18 {b).

Also, turn the armature around so that none of thesolder will drop in where it will be likely to give case a coil has a short circuit within itself, it will, ofcourse, burn out whether it is disconnected from the othercoils or not, and in so doing
