How to test automotive relays with multimeter?

Testing automotive relay is not very complicated as you can see. Using the continuity test, you will know whether the relay is working or not. The test will be easy when your meter is set to multi-tester. Using the multi-tester, you will be able to view the relay’s contacts. Check these contact points for continuity. If there is no continuity or short-circuit found, then your relay is faulty. The next test will determine if the switch is faulty

How to test automotive relay with DMM?

Set the DC voltage of the DMM to the value you got from the previous step. Connect the DMM to the circuit. Then, press the relay s Test button and compare the coil’s output to the DMM’s output. If they’re the same, the relay is working properly. You can also switch the DMM to Measure mode and read the current passing through the coil.

How to test automotive relay with multimeter?

Now we will test the working of the automotive relay with the multimeter. We are going to test the working of automotive relay with the following procedure: First, place the automotive relay on the test bench and connect the test leads to it’s terminals. Then, switch on the power supply to the coil, followed by the battery. Once the coil is powered, switch off the power supply to the coil and observe the output of the automotive relay. If the coil is working then you will observe

How to test automotive relays with multimeter and continuity tester?

A car’s electrical system is designed to work, and when the system fails to do so, it can be quite an expensive problem to deal with. So always check your car’s relays for continuity with a multimeter and continuity tester. If you come across any that are not passing, don’t just replace them as before. Contact an experienced mechanic to have them fixed.

How to test automotive relays with multimeter test lead?

Using a basic multimeter, you can test the continuity of automotive relays. You can test it by using the continuity test in the menu of your meter. Connect the two probes of the test lead to two contacts of the relay, one to the common (or the coil ) and the other to the NO (Normally Open) contact. If you have a switch in the NO (Normally Open) contact, turn it on. If you don’t have a NO (
