What is the method for direct starter activation?

[LaNova]

The method for direct starter activation is: 1. The starting time should not exceed 5 seconds, and after starting, let the engine idle for 2 minutes to allow the battery to recover; 2. When starting in low temperatures, keep the battery warm to ensure it has sufficient starting capacity. Reasons for starter idling: 1. Disconnection between the armature shaft and armature core; 2. Improper adjustment of the gap between the engine, starter drive gear, and thrust washer; 3. Damage to the flywheel ring gear; 4. Fault in the magnetic switch, such as open circuits in the pull-in and hold coils, or burning of the wiring, magnets, contact disk, and contact surfaces. A starter is a small gasoline engine equipped with a clutch and transmission mechanism. It has high power and is less affected by temperature, making it capable of starting large internal combustion engines and suitable for extremely cold regions.

In my over 20 years of driving experience, I've encountered several starter failures. The direct starting method is actually quite simple: locate the starter under the hood, usually there's a small terminal connection on the side of the engine. Use a thick jumper cable to connect one end to the battery positive terminal and quickly touch the other end to that small terminal - this directly completes the circuit and gets the engine turning. However, this carries high risks: you must wear insulated gloves and act swiftly to avoid short circuits or electric shocks; tools touching metal body parts can cause sparks that may blow fuses or even start fires. I only use this as emergency roadside assistance when stranded in remote areas. Afterwards, professional garage inspection of the entire electrical system is mandatory to prevent recurring issues. Regular maintenance like quarterly cleaning of battery terminal oxides can significantly reduce starter problems, saving money and ensuring safety.

When I first started learning car repair, I encountered a starter motor issue. I tried the direct starting method: first, turn off all the engine power for safety, then open the hood, locate the control terminal of the starter motor, and gently tap the terminal and the battery positive with an insulated screwdriver for just a brief moment—the starter motor buzzed to life. You need to stay focused during the operation; don’t hesitate or hold the connection too long, or it may overheat and damage components. Beginners might panic, so I recommend using a voltmeter to check if the battery is functioning properly first. This method works but shouldn’t be relied upon, as it can easily damage the relay or control unit. Afterward, head to the repair shop promptly to replace the faulty parts. To prevent issues, regularly check if the car lights and horn are working properly, as these can reflect the health of the electrical system and avoid sudden starter motor failure.

Direct starter activation is primarily used for testing purposes, such as when electricians temporarily connect power to rotate the engine during fault diagnosis. The method is simple: use jumper cables to connect the battery's positive terminal to the starter's small terminal, activating it momentarily. However, this operation carries high risks and is not suitable for untrained car owners to attempt casually, as it may cause accidental short circuits or electric shock hazards. From a safety perspective, protective gear must be worn, and the procedure should be performed in an open, well-ventilated area. I highly recommend entrusting this task to professional technicians, as they use proper equipment and operate much more safely. In daily vehicle use, pay attention to any abnormal noises or delays during startup, as this can help detect potential starter issues early.
