The 2G DSM alternator wiring diagram is an important aspect of any Mitsubishi Eclipse or Eagle Talon owner’s manual. The alternator plays a crucial role in powering the car’s electrical system and keeping the battery charged. This guide will provide an overview of the 2G DSM alternator wiring diagram, including common issues and solutions.
Understanding the 2G DSM Alternator Wiring Diagram
The 2G DSM alternator wiring diagram features three main components: the alternator, the battery, and the vehicle’s electrical system. The alternator is responsible for generating electricity and charging the battery. The battery stores the electrical energy and provides power to the vehicle’s electrical components. The electrical system includes various components like lights, radio, and other electrical accessories.
The 2G DSM alternator wiring diagram includes four main wires that connect these components. These wires are:
| Wire | Color | Purpose |
|---|---|---|
| L | Black/Red | Exciter wire to turn on the alternator |
| S | White/Black | Battery voltage sensing wire |
| B+ | Large red wire | Connects to the battery positive terminal |
| B- | Large black wire | Connects to the battery negative terminal |
Common Issues and Solutions
Issue 1: Low Charging Voltage
If your vehicle’s alternator is not charging the battery properly, one potential issue could be low charging voltage. This issue can be caused by a faulty voltage regulator or a loose connection in the alternator wiring. To test for this issue, you can use a voltmeter to measure the voltage output of the alternator. If the voltage output is lower than the battery’s voltage, you may need to replace the voltage regulator or check for loose connections.
Issue 2: High Charging Voltage
Another common issue with the 2G DSM alternator wiring diagram is high charging voltage. This issue can be caused by a faulty voltage regulator or a damaged alternator diode. To test for this issue, you can use a voltmeter to measure the voltage output of the alternator. If the voltage output is significantly higher than the battery’s voltage, you may need to replace the voltage regulator or the alternator diode.
Issue 3: Dead Battery
If your vehicle’s battery is consistently dying, one potential issue could be a faulty alternator. A faulty alternator can cause the battery to drain quickly and become completely dead. To test for this issue, you can use a multimeter to measure the alternator’s output voltage. If the output voltage is significantly lower than the battery’s voltage, you may need to replace the alternator.
Issue 4: Loose Connections
Loose connections in the 2G DSM alternator wiring diagram can also cause issues with the charging system. To check for loose connections, you can inspect the wiring harness for any signs of damage or loose connections. Tightening any loose connections can help improve the charging system’s performance.
Issue 5: Bad Alternator Belt
The alternator belt plays a crucial role in powering the alternator and charging the battery. A worn or damaged alternator belt can cause issues with the charging system. To check for this issue, you can inspect the alternator belt for any signs of damage or wear. Replacing the alternator belt can help improve the charging system’s performance.
Conclusion
The 2G DSM alternator wiring diagram is a critical component of any Mitsubishi Eclipse or Eagle Talon owner’s manual. Understanding the wiring diagram and common issues can help you diagnose and fix any charging system problems. By following these guidelines, you can ensure that your vehicle’s electrical system is functioning properly and keeping your battery charged.
