Starting & Charging System Video Guide

Understanding the Problem

While professional installers know the ins and outs of starting and charging systems, many drivers and DIY enthusiasts lack knowledge about how these systems work, proper maintenance, and voltage testing practices.

“Proactively identifying the warning signs can help drivers avoid costly repairs and stay safely on the road.”

The Goal

This video series is designed to raise awareness and help viewers recognize the warning signs that indicate potential problems with the starting and charging system.

“With this video series, we aim to empower professional mechanics to better educate their customers and encourage DIYers to maintain their vehicles with confidence.”

Key Issues

  • Lack of Awareness: Many people don't understand how critical these systems are for their vehicle’s overall performance.
  • Maintenance: Regular inspection and upkeep are necessary, but most drivers are unaware of the maintenance routines required.
  • Voltage Testing: This essential diagnostic step can detect early issues, but is often overlooked or misunderstood.
“Regular maintenance and early detection of issues can save significant time and money in the long run.”

Our Solution

Starting and Charging 101 shows the warning signs that are often ignored and provides practical advice on maintaining starting and charging systems.  The video outline the components of the starting and charging systems by covering the following: 

  • The crucial role of the battery in powering various vehicle systems and maintaining overall performance.
  • The importance of a reliable starting system for consistent engine ignition.
  • The significance of an efficient charging system to keep your vehicle running smoothly.
  • Essential maintenance tips to ensure the longevity and reliability of your vehicle's components.
  • Basic check procedures to help you identify and troubleshoot potential issues.

A Call to Action for Professional Installers

We ask professional installers to share the video below with their customers to help them understand the maintenance practices that will keep their starting and charging system in top shape. Share it with customers and DIYers to spread awareness and promote safer, proactive vehicle care!

Starting and Charging FAQ

 

The Battery

What is the role of the vehicle battery?
The battery stores and supplies power to the starter motor and ignition system, allowing the engine to start and run smoothly. It also provides extra power when the vehicle’s electrical loads exceed the charging system’s supply, acts as a voltage stabilizer, and supplies power to various modules and systems when the vehicle is not running.

How should I maintain my vehicle battery?
Regular maintenance includes inspecting and testing the battery, cleaning its terminals, and ensuring the connections are clean and tight. This helps keep the battery in optimal condition for any driving condition.
 

The Starting System

What components make up the starting system?
The starting system consists of a battery, starter motor, starter solenoid, starter relay, ignition switch, and the connecting wires and cables.
How does the starting system work?

When you turn the key or press the ignition button, it activates the starter motor, which cranks the engine until it starts. If the starter is not working properly, the vehicle won't start.

What maintenance is required for the starting system?
Inspect the starter to ensure the connections are clean and tight, and verify the proper functioning of the starter motor. Regular maintenance is vital for reliable performance.

 

The Charging System

What is the function of the charging system?
The charging system maintains the battery's state of charge while the engine is running. It consists of an alternator or generator, a voltage regulator, the battery, and connecting wires. The PCM (powertrain control module) also helps control the alternator and charging system on many newer vehicles.

How does the alternator work?
The alternator or generator converts mechanical energy from the engine and drive belt into electrical energy. The voltage regulator ensures the charging system maintains the correct voltage range.

What maintenance is necessary for the charging system?
Regular maintenance includes inspecting and testing the alternator, cleaning and tightening all electrical connections, and checking the drive belt for wear and proper tension.
 

Voltage Testing

How do I check the battery voltage?
Use a digital voltmeter to measure the voltage across the battery terminals. With the engine off a healthy battery should read around 12.6 to 12.9 volts. If it’s significantly lower, it might need charging or replacement.

How do I test the alternator’s charging voltage?
Start the engine and measure the voltage again. It should read between 13.5 and 14.4 volts, indicating that the alternator is charging the battery. If the voltage is too high or too low, it may signal a problem with the alternator.

How can I diagnose issues with the starter motor?
Turn off the engine and try starting the vehicle. If you hear a clicking sound or the engine doesn’t crank, it could indicate an issue with the starter motor, starter solenoid, electrical connections, or the battery.
