Have you ever driven an automotive and used indicator light that worked correctly? No big deal, they should, right? But have you been in a position where you indicate a left turn, but the vehicle indicates to the right or pulls both the hazards? Well, I have been there, and trust me; you do not want to have the experience ever! The aggravation that comes with short circuit boards that transmit power to the lights, signals and so forth is beyond comprehension, especially where the user does not understand the relays that are associated with the transmission of power to the designated areas. The relays in a car are myriads, and they all have different roles. Understanding g a few relays is better than not comprehending the working of your automotive.


What is a relay?

Simply put; relays directs/ give orders/signals. The relays act as initiators and send a signal to something to take some action. In a circuit, relays are the main proponents controlled by the circuit system of a particular duty.  For instance, a relay sends a notion to the signal to flash, windows to go up or down and so forth. In a car, the relay functions as a messenger that sends out the message to various car parts.


Relay Types

Timer relays

these basically act as the timers within a system. The timer relays hold the information in which a certain action is taken at certain duration. The timer relays promote the working of the dashboards, for instance, the oil change when the oil needs replacement and so forth. The electrical system converts the message sent by the relay and indicates on the dash when the oil needs changing.

Glow Plug Relays

these initiate when the electrical system needs to glow. In a car, a diesel engine car may be a good example. The car needs to glow its dash using the ignition system, which is powered by the glow plugs.


Flasher relays

These control the hazards with a controlled system of opening and closing of the contact between the flashing of the light. They control how the system will operate for the right or left signals.


Fuel Injection relays

The relays relate with the Engine System to control the amount of fuel from time to time. Mainly augments with the petrol engines.


Importance of Relays

  •    They initiate the car startup processes
  •    They promote the efficiency in the dashboard so that the driver is able to observe the dash without any fuss
  •    Helps in the addition of extra lighting mechanisms that may not have been altered at the car manufacturer level
  •    Relays have been used to disengage car theft mechanisms by adding hidden switches within the car which only the owner knows where to press for the car to start.
  •    The relays are also used for warning the drivers when the car lights are left running, windows are unlocked, or the doors are open among other ways.
  •    Relays help with the terminal layout setting and electro wiring of the automotive where certain relays are set to carry various duties.

Comprehending the major operations of various relays is quintessential in the how you handle your car should you ever experience a menace with the signal system, the dash, or the car startup process. It is prudent to grasp some knowledge about the relays and how each one can affect your car functions. Although the relays fall in the technical groups of your automotive, knowing a thing about them makes you wiser with regard to the mechanical complexity involved. You only need to stop by our shop and seek more information on exactly what type of relay you need to either upgrade or replace your vehicle.
