If the multimeter reviews 1 or shows ol, it’s overwhelmed. Here are the best ways to test a relay with a multimeter: This is the easiest way to do it out of the car and t.
You will need to try a higher mode such as 200kω mode or 2mω (megaohm) setting.
How to test a relay without multimeter? Below are the methods how to test fuel pump relay without a multimeter: Check resistance of the coil.
And one of the best ways to do this is to use a multimeter with an ohmmeter setting and then measuring the resistance values.
This video shows you how an automotive relay works and how you can test it using an digital multimeter. Testing continuity without a multimeter. A continuity tester is a small device that is powered by batteries.
Professionals do not recommend doing this test.
How do you test an electromagnetic relay? Also read our guide on how to test an alternator with a multimeter or without: Remove the test light, set the multimeter to dc volts, and touch the leads across the switch pins or test light connectors, as shown.
The coil controls the opening and closing mechanical actions of the contacts.
If the multimeter reviews 1 or shows ol, it’s overwhelmed. Here is how you test a car relay the correct way. This is the easiest way to do it out of the car and t.
First, you can use a test light to check if it is functioning.
With the relay removed from the fuse box, the multimeter set to measure dc voltage and the switch in the cab activated, first check to see if there are 12 volts at the 85 position in the fuse box where the relay plugs in (or wherever the relay is located). If you get resistance, us. Test the coil terminals of the relay with an ohmmeter.
