When it comes to solenoid valves in the industrial hydraulic, pneumatic, and processing world it contains a coil. My question what is the correct way to test the coil? I was told if you put the setting of your digial multi-meter to the ohms setting and place it across the two terminals that you should get an ohm reading which indicated that the coil is good. If you test a coil and you get an OL reading then that means that you have a defected coil and you need to replace it with a new one. Is this the correct way to test a coil? If not then what is the best way to test a coil to a solenoid to a valve?
