The starting relay is the most important and most overlooked part of the car's ignition system. Its role is to redirect the power from the battery to the starter solenoid valve, and then turn on the starter when the engine is idling. Only when the relay is operating normally can you turn the vehicle on and off normally.

Although you may not encounter the problem of Automotive Relay at present, it is a part about whether your car can drive. Once it is worn out, for your driving safety, please contact professional maintenance personnel to replace it in time.

It is worth noting that most modern cars are equipped with electronic ignition switches activated by a remote control. The electronic chip of the remote control key communicates with the kinetic energy on the car, allowing you to achieve the effect of remote starting. But sometimes the remote control key will affect the relay and convey the wrong error message.

The Automotive Relay Manufacturer lists some symptoms of relay damage or wear. If you notice these similar symptoms, make sure you contact your local professional technician to thoroughly inspect your vehicle as these symptoms may indicate problems with other components as well.

1. The vehicle cannot start.

The most obvious symptom is that when you ignite, the car cannot start, which means that there is something wrong with your relay. The electronic key does not have a manual ignition switch. It works by sending a signal to the relay once the key is inserted or the start button is pressed after power is applied.

Once you can't start the vehicle with the key or electronic key, then there is a high probability that the failure of the relay will cause problems.

Once this kind of problem occurs, you can't start the car no matter how many times you try. When the circuit is not completely damaged, you will hear a click when you start, but no matter what the circuit is, you need to go Perform repairs to ensure driving safety.

2. When the engine is started, the start relay remains connected.

Normally, when you start the engine and release the key or after pressing the start button to start the car. The circuit of the start relay closes and interrupts the power to the start relay.

But when you start the engine, the start relay remains connected, which means that the main contacts of the start relay are likely to be welded together in the closed position.

If the contacts of the start relay are kept connected for a long time, it will cause damage to the starter, circuit, relay and transmission flywheel. In order to stop the loss in time, it needs to be replaced as soon as possible. Our company also has THT Relay on sale, welcome to consult.
