Does AutoZone Test Relay?

AutoZone is a retailer of automotive replacement parts and accessories. The form has an extensive product line for cars, sport utility vehicles, vans, and light trucks, including new and remanufactured automotive complex parts. It also offers maintenance items, accessories, and non-automotive products. The retailer operates in the United States, Puerto Rico, and Mexico.

Does AutoZone Test Relay?

Yes AutoZone tests relays. A relay acts as the on and off switch that controls the ignition, idle speed, and several other import systems of a vehicle. AutoZone offers a relay of top-notch quality to ensure fast response in your car. When your relay needs to be changed, you can trust AutoZone to get the job done at an affordable price. A relay can be tested with a jump cable, a voltmeter, an ohmmeter, or a test light. Suppose the terminals are accessible and a computer does not control the relay; the fastest method will be to use a jump cable or a test light. If there is no voltage, then the relay coil is defective.

Will A Relay Click If It’s bad?

If your relay turns on and off rapidly, it will produce a clicking noise in your car’s fuse box. This can result from computer failure, resistance in the ground wire for the control side of the relay. It can also be caused by high resistance in the power supply to the control side of the relay.

What Happens When A Relay Goes Bad?

When a relay goes bad, your vehicle will experience different problems and cause stalling of the car, draining and damage to the battery, and loss of power in the dashboard lights.

Why Is It Essential To Test The Relay?

Testing the relay ensures that faults are located in time; defects can cause significant equipment damage and lead to failure in a worst-case scenario. Relay testing provides an affordable solution to protect essential equipment components and avoid the expense of downtime or repair of damaged equipment.

Relay testing involves simulating standard relay operating conditions that ensure they are functioning well and in good condition. For example, it determines if a relay’s coil collapses while switching positions when the vehicle operates.

 If coils collapse while the system is running, this is often due to arcing and carbonizing over long-term use. This causes the transient voltage to move through the system and cause equipment damage. To prevent this often snubber circuits are used if the course fails; they might go unnoticed and cause the relays to fail.

How to Test a Relay On A Circuit Board

Relays are usually supplied with 12v directly from the battery of the vehicle. The electrical resistance of the coils varies depending on the manufacturer of the relay and the type of the relay. Still, in general, a typical value is between 50 ohms and 200 ohms.

Conclusion

Any driver relies on a quick start-up every time. If your vehicle struggles to achieve this, you should check if your relays are in good working conditions. You can get your relay tested at AutoZone; the retailer has the solution for replacing relays at an affordable price. In addition, their relays are custom designed for your specific year, make, and model, so you can rest assured that the relay product is perfect for your vehicle.
