Ohmmeter checks should be made with the power off
and the circuit open (to be certain, disconnect one lead
to the magnet). Average resistance for the 90 volt series
is 220 ohms; for the 24 volt, 20 ohms; and for the 6 volt
series, 1.5 ohms. A very high or infinite resistance
reading would indicate an open coil.
If the above checks indicate that the proper voltage and
current is being supplied to the magnet, mechanical
parts should be checked to assure that they are in good
operating condition and properly installed.
