8 significant symptoms and solutions of damaged starter relays

The starter relay has malfunctioned

A starter relay is an electrical component in a vehicle or other equipment that can serve as the main agitator for starting an electric motor or driving a system in other ways, thereby further saving voltage. However, after a period of time, the initial relay may malfunction, causing your device to fail to start properly. Identifying faults or symptoms of faulty starting relays can help you take action to prevent greater damage. In this article, we will comprehensively explain the 8 most important warning signals of fault starting relays and their solutions

The starting relay does not work after the first symptom appears. The most common reason is that the relay cannot connect the current, so there is not enough power to start the motor. You may hear a 'click' sound or nothing happening.

Solution:
Determine if the relay has burned out. Then replace the faulty relay with a new one that is not functioning properly, ensuring that the model you installed is supported.

When the starting relay malfunctions, the equipment will emit strange starting noise. It's like hearing a "hissing" sound, or anything that causes the relay to make an unstable sound, such as a friction sound or perhaps just a lack of contact sound.

Solution:
Check the relay to ensure it is not worn or damaged. If a malfunction occurs, it is best to replace the relay.

If the starting relay is damaged, it may not be possible to control the current flowing into the motor during startup, resulting in overload. This may burn out the electrical components of the equipment and pose a risk of fire.

Solution:
Use an ammeter to check for overload. If there is overload, the relay and circuit should be tested. If there is a fault, it should be replaced.

If the starting relay malfunctions, it will cause the battery power to not be delivered properly. Due to the inability of relays to effectively switch current, it is difficult to drive the motor for a long time after each charge, resulting in a shortened battery life.

Solution:
Use a multimeter to check the battery voltage and monitor if the battery level drops sharply. If it's a relay issue, we may need to replace the starter relay.

Use a multimeter to check industrial equipment

Long term operation of the starting relay or poor electrical contact can cause the communication overload protection device to overheat. This not only affects the overall performance of the device, but may also damage other components.

Solution:
When starting this device, touch the relay to determine the temperature. If the relay overheats, please disconnect the power as soon as possible; Check the resistance of all contacts and replace any faulty circuits.

Internal circuit of relay: If overloaded or used for a long time under harsh conditions. Example situation: burnt or discolored. This is indeed a flashing LED indicating that the relay is overheating.

Solution:
Check if there are any burnt or discolored marks on the relay housing. We must replace the relay now for the machine to function properly.

The starting performance of the engine may change and decrease over long-term use, because after a long period of use, the electrical contacts of the starting relay may also have poor conductivity due to oxidation or corrosion.

Solution:
Regularly test the contactor contacts and remove oxides or corrosive substances. Therefore, if we find that something is damaged, we need to install a new relay.

In other cases, starting the relay may cause internal short circuits or open circuits, which can lead to electrical faults.

Solution:

Step 3: Use an electric meter to check if the relay is used for short-circuit points or open circuit columns. The faulty relay needs to be replaced.

If you are experiencing a problem with a damaged starter relay, remember to diagnose based on the above symptoms and take appropriate solutions. This can avoid more serious malfunctions and ensure the normal operation of the equipment. If you have any requirements for relay products, you can contact us for solutions.
