Listen carefully to the tape-recorded text two times and render it in English using the words and word-combinations from the list: short circuit, to burn out, to locate, shorted point, leads of a test lamp, to move away, lamp will flicker, to remove the coils, to insert a strip of.

A short circuit between these two windings will permit a current to flow through a part of the starting winding continuously while the motor is in operation, and in time will burn out the starting winding. To locate the shorted point, the windings are disconnected from the terminals and one of the leads of a test lamp (connected to the line) is connected to the running winding, and the other lead is connected to the starting winding. The lamp, will light, since current flows from the running winding through the shorted point to the starting winding. The starting winding is then moved away at various places in the stator. If the shorted point is moved, the lamp will flicker or go out. If the snorted point cannot be determined in this manner, it will be necessary to remove the coils of the starting winding one ^>-at a time until it is located.

The short circuit can usually be repaired by inserting a strip of varnished cambric in the slot between the two windings.
