What Are the Reasons for the Car Starter Motor Not Responding?

[SanLucy]

Reasons: The battery is low on power; the starter fuse or relay is damaged; the ignition switch is faulty; poor contact in the starter's solenoid switch. Below is a detailed introduction to car relays: 1. Function: The basic role of a car relay is to act as an 'automatic switch' that uses a small current to control the operation of a larger current. It plays a role in automatic regulation, safety protection, circuit conversion, and switching in the circuit. 2. Selection Based on Usage Environment: The usage environment mainly refers to temperature (maximum and minimum), humidity (generally the maximum relative humidity at 40 degrees Celsius), low air pressure (can be ignored below 1000 meters in altitude), vibration, and impact. Additionally, there are requirements for packaging methods, installation methods, dimensions, and insulation. Due to differences in materials and structure, relays can withstand varying environmental mechanical conditions. Using a relay beyond the environmental mechanical conditions specified in the product standards may damage it. Therefore, relays should be selected based on the environmental mechanical conditions of the entire machine or higher conditions.
