Starter Motor: The Definitive Guide   Every vehicle, whether a modern or older model will have a starting system. At the heart of it all is the starter motor. Also known as self-starter, electric starter motor or cranking motor, the automotive starter motor is such as an essential device. The starter is so important in [...]

Before we discuss the starter solenoid problems and bad starter solenoid symptoms, let’s figure out what is a starter solenoid first. A starter solenoid is a major component of an automotive starter system. It helps in starting the engine by performing two functions: 1. Acting as a switch to deliver a high current from the […]

Starter Solenoid Manufacturing and Production Standard QC/T 810-2009 This Starter Solenoid Manufacturing Standard is issued by Chinese Ministry of Industry and Information Technology. The standard reference code is QC/T 810-2009.   This guide is designed to help Chinese starter solenoid manufacturers manage their production of car starter solenoid switch. The test methods and inspection ways in […]

Recently I asked our engineers a few questions about the starter solenoid:

“Do you know how to replace a starter solenoid?”
“No.”
“Do you know how to repair a broken starter solenoid?”
“Well, I know how to assemble a starter solenoid.”
“Do you know how to start your car with a broken starter solenoid?”
“I guess you’d better call for help?”
“Do you know……”

Starter Solenoid plays two roles in the starter, one is connecting to the main circuit to make the starter rotation; the other is pushing the pinion gear to mesh with engine flywheel ring gear by shifting fork. Starter Solenoid technical requirements: large suction, large stroke, reliable break-make of contacts, large electric current, small size and […]

 A starter relay may be bad if you see the following symptoms An engine that won’t start at all( remains silent even after you turn on the ignition key) You hear multiple clicks but without the engine starting The starter relay remains on even after you have turned the ignition key off The ignition key […]

Learn how to write a starter relay is easy. You only need a few wiring tools like a pair of pliers, spanners, some wires of appropriate gauge, and a little technical know-how of how the starter relay operates. In simple terms, the starter relay uses the minimal current from the ignition switch circuit to induce […]

The starter relay is a very important component in an automotive ignition system. If it fails, it can mean the vehicle not starting.

Many people think a starter solenoid switch and a starter relay to be the same, which is not true. (Even wiki claim they are the same thing in the different name.) They are way different in terms of their construction, working, and functions.

The typical starting system wiring diagrams can divide into non-relay control type, single starter relay control type, and security starter relay control type. The specific circuit needs to be respectively learned referring to different typical control circuits. The main function of car starting circuit is using the small current from the car battery to control the […]
