Testing for Short Circuits Between Run and Start Windings
Testing for Short Circuits Between Run and Start WindingsA short between run and start windings may be determined by using the ammeter and line voltage to check for continuity between the two separate circuits. Disconnect the run- and start-winding leads, and connect the instrument as shown in Figure 9-16. Set the meter on voltage. A full-line voltage reading will be obtained if the windings are shorted to one another.
