What is the reason for the clicking sound from the motorcycle relay?

Although cars are a very popular means of transportation nowadays, motorcycles remain the favorite driving tool for many. However, due to the low popularity of motorcycles, many riders do not know what it means when the motorcycle relay makes a "click" sound. So, let's talk about the reasons why the motorcycle relay makes a clicking sound and what the function of the relay is.
What is the reason for the motorcycle relay making a clicking sound?
1. Loose screws on the motor can cause poor contact of the relay's main contacts, or the resistance may have aged and increased, leading to the motorcycle relay making a clicking sound.
2. The starter motor coil may be burned out, the relay coil may be disconnected, or the starter clutch may be stuck, causing the relay to make a sound.
3. A depleted motorcycle battery can also cause the relay to make a sound. Therefore, it is necessary to measure the voltage with a multimeter at this time.
The relay is an electrical control device that causes a predetermined step change in the electrical output circuit when the change in input quantity meets specified requirements. It has an interactive relationship between the control system and the controlled system.
What is the function of the relay?
The relay plays a role in automatic regulation, safety protection, and switching circuits in the circuit. In central air conditioning control systems, relays are often used as switches for power circuits of compressors, fans, motors, etc.
