ohmmeter to measure the resistance. Use the high-
est resistance indication. The coil should read
52 ohms ±10%. Remove and replace contactor if re-
sistance readings indicate a short circuit in both di-
rections or if there is an open circuit in both direc-
tions. Make sure coil wires are connected to the
proper terminals.
