ELECTRICAL DATA
TO DETECT OPEN AND SHORT CIRCUITS IN
ELECTRICAL COMPONENTS
Open circuits in the coils of electrical components may
be detected by isolating the coil and checking for continuity
with an ohmmeter or with the unit in series with a light or
bell circuit.
Shorted turns are indicated by a current draw substantially
above normal (connect ammeter in series with suspected
element and impose normal voltage) or D.C. resistance
substantially below normal. The current method is
recommend for coils with very low D.C. resistance.
Motor current draw in the stator should be measured with
the rotor in place and running. Brake coil current should be
measured with the core iron in operating position.
