In relays, a player passes the authority to proceed to the next step or to the finish line to the player next to him. The first player can't bypass his teammates to proceed by himself. This also goes for some of your vehicle's components. Power needs to be supplied in the right manner. To make sure the proper sequence is achieved, a Relay is used. This component is basically an electrically operated switch that completes or interrupts the flow of current in a certain circuit within your car. It is made up of a coil wire that surrounds a soft iron core, an iron yoke, a movable iron armature, and a set of contacts. You'll be surprised by the number of relays that your car has. There are relays in the auxiliary lights, the ignition system, and even in the cooling system. Even though the Relay is just a small component, faulty relays will affect the performance and comfort that you get out of your car. Replacement is the best solution once this happens. However, make sure you know the particular type required by particular automotive systems. For a selection of quality automotive relays, Auto Parts Warehouse offers different types, so you'll surely find what you need. Shop now and take advantage of big discounts on high-quality products!
The Various Relays in Your Car
You can't count just how many relays there are in your vehicle because of their great number. You have relays controlling the safety features in your car (the ABS system, the airbags, and the anti-theft alarm), your various car lights (the headlights and fog lights, as well as the turn signals and the parking lights), and other basic functions that enable your car to run well (glow plugs and cruise control). All of these relays work the same way, only they power different parts.
Two General Types of Relay
Although there are different relays in your vehicle, these parts can only be generally categorized into two, as follow:
What it is: This is a relay that receives low voltage signal across its terminals and then converts the fluctuations created by such signals into a mechanical force that actuates the relay's electrical contacts.
Advantages: This type of relay is relatively cheap. Using it is also easy, so there's no hassle involved.
Disadvantages: This relay is mechanical in nature, and it is that which serves as its weakness. It doesn't respond as quickly and it may have a shorter life because of its wear components.
Solid State relay
What it is: This relay operates in the same manner, only that it isn't mechanical in nature. It is purely electrical, and it is composed of a transistor instead of moving parts.
Advantages: This type of relay has faster response time. It is also highly reliable, and it generally features a longer service life.
Disadvantages: Despite the many benefits, the solid state relay also has some disadvantages. One of the most common is its susceptibility to overheating.
Under these two general types of relay, there are still other relay designs, some of which are in popular use today while others have already become rare. If you're looking for a new relay for your vehicle, you might want to consider the different types available. Find one that is compatible with your vehicle make and model to ensure efficient function.
Automotive Relay Replacement
Can you count the exact number of relays that you have in your vehicle? Chances are, you can't-they're just too many to count. Majority of the electrical components in your vehicle are operated by a relay: the starter, the headlights, the fuel pump, and many other components. It is the relay that controls the electrical signals that get into these components so that they can work well. Once the relay is damaged, your crucial car components won't function at all. Good thing it's easy to replace the relay.
Difficulty Level: Easy
Tools You'll Need:
- Test light
- Flathead screwdriver
- New relay
Step 1: Disconnect the battery for safety precaution before starting the process.
Step 2: Find the relay to replace. Depending on your vehicle and depending on the type of relay, the location may vary. Possible locations are the fuse box in the engine compartment or behind the dashboard near the steering wheel. If you're not sure of the location, check your vehicle owner's manual.
Step 3: Depending on the type of relay, you may find that it is held in place by a bolt or that it simply connects like a plug. In case it's held by a bolt, you will need a wrench to unbolt it. Otherwise, you can pry it out using a flathead screwdriver. There are set-ups where you may need to disconnect a fuse and a connector before you can completely take the relay off.
Step 4: After the removal process, all you need to do is to mount the new relay the same way the old one is mounted. Then, reconnect your vehicle battery and test the component that the relay controls to see whether it's already working well.
With a new relay mounted, you're ready to drive without hassles again.
