Relay can be checked by usingA Multimeter Dial gauge with magnetic stand Ammeter

A relay can be checked using a multimeter by following these steps:

1. Disconnect the relay: Before you start testing, make sure to disconnect the relay from the circuit. This is to prevent any damage to other components or the relay itself.

2. Set the multimeter: Set your multimeter to the resistance setting (Ohms). This will allow you to check if the relay coil is good.

3. Test the coil: Connect the multimeter leads to the relay coil terminals. You should get a resistance value. If the multimeter shows a resistance value, it means the coil is good. If it shows no resistance or infinite resistance, the coil is bad.

4. Test the switch: Next, you can test the switch part of the relay. Set your multimeter to the continuity setting. Connect one lead to the common terminal and the other to the normally open terminal. If the multimeter beeps, it means the switch is good. If it doesn't beep, the switch is bad.

5. Reconnect the relay: After testing, make sure to reconnect the relay to the circuit.

Remember, always follow safety precautions when working with electrical components.
