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 DC resistance substantially below normal.
The current method is recommend for coils with very low DC
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.
