- Due to factors beyond the control of FixItSam, it cannot. You will find the resistance of the relay coil. The purpose of testing a relay is to find, whether it is good or bad.

To test a relay, you need to have a multimeter or an ohmmeter.

Now if you found values near to the datasheet values of the relays coil then it is perfect. If the resistance falls with the range mentioned in the datasheet. The polarity of probes on terminals doesnt matter because we are finding resistance. The First Step Is To Test The Coil of Relay.
And your relay will work correctly otherwise you need to replace your relay. So it is crucial to test a relay if it stopped working before you replace it or throw it away. In the datasheet you will also get the tolerance value of the coil. It contains only an integrated circuit memory chip that is used to store data.
