How do you test a relay with a 9v battery?
You can test a relay with and without a 9 volt battery. If you apply 9 volts to it and it's sufficient to turn on the relay, the NO switch will close and then have continuity with common. If you don't apply voltage, the NO switch will be open and not have continuity with common. You can use these continuity and resistance checks to test a relay to see if it works.
How do you tell if your 1998 Audi A4's switch is bad or if it is just a relay?
best way to test a relay is remove it from board, get a 9v square battery and touch the switching terminals on the relay, the relay should click if its working. You can then test resistance through the relay. You can also check the feed to the relay, if theres pwer to the switching terminals on the relay, chances are the switch it ok. If no voltage, switch or wiring.

2001 Saturn constant horn blowing?
Typically, that problem would only be caused by a faulty horn relay or a damaged horn contact switch inside the steering column. A frayed wire that rubs on a metal part of the vehicle. Since the relay is the easiest part to test, remove the relay and replace it with a similar relay FOR TEST PURPOSES ONLY. If the horn works properly with a replacement relay, put the relay you used for testing back and purchase a new horn relay. If the test relay left the horn ON, you probably have a damaged horn contact switch, in which you will need to replace the faulty component.
How do you test fuel pump Relay on a 1988 gmc 1500?
Type your answer here... you don't... there is no way to test a faulty relay. Just buy a new relay and install it. If the problem is fixed, then the old relay was bad. If the problem still exists with the new relay installed, then the old relay is still good. Most auto parts stores are good for returning products, even electrical parts.
How can you test relay if good or bad?
To test a relay, first disconnect it from the circuit and use a multimeter to check for continuity across the relay's contacts when the coil is energized. If the multimeter shows continuity when power is applied to the coil, the relay is functioning properly. You can also listen for a clicking sound when the relay is energized, indicating that the contacts are closing. If there's no continuity or the clicking sound is absent, the relay is likely defective.
Where is the relay for the fuel pump on a 1989 Chevy van and how do you test it?
