The Mitsubishi Storm L200 is a reliable workhorse, known for its durability and performance. But like any vehicle, it relies on a healthy alternator to keep everything running smoothly. The alternator is a crucial component of your L200's electrical system, responsible for charging the battery and providing power to the various electrical components while the engine is running. Without a functioning alternator, your L200 would quickly grind to a halt. Let's dive into the world of the Mitsubishi Storm L200 alternator, exploring potential problems, replacement options, and associated costs.

Understanding the L200 Alternator

Before we get into the nitty-gritty, let's understand the basic function of your L200's alternator. Think of it as a mini power plant for your truck. When your engine is running, the alternator, driven by a belt connected to the engine's crankshaft, generates electricity. This electricity serves two primary purposes:

• Charging the Battery: The alternator replenishes the battery's charge, which is depleted when starting the engine and running electrical accessories.
• Powering Electrical Components: The alternator provides the necessary power to run the headlights, radio, air conditioning, and other electrical systems while the engine is running.

A typical L200 alternator outputs around 12-14 volts, ensuring all electrical components receive adequate power. Without a properly functioning alternator, your battery would quickly drain, leaving you stranded.

Common Mitsubishi Storm L200 Alternator Problems

Even with proper maintenance, your L200's alternator can experience issues over time. Here are some common problems to watch out for:

• Dead Battery: This is the most obvious sign of an alternator problem. If your battery frequently dies, even after being charged, the alternator may not be charging it properly.
• Dim or Flickering Headlights: If your headlights are noticeably dimmer than usual, or if they flicker, it could indicate the alternator is not providing enough power.
• Warning Lights: The battery warning light or alternator warning light on your dashboard may illuminate, signaling an issue with the charging system.
• Strange Noises: A whining or grinding noise coming from the alternator could indicate worn bearings or other internal damage.
• Electrical Issues: Problems with other electrical components, such as the radio or air conditioning, could be related to a faulty alternator.
• Stalling: In some cases, a failing alternator can cause the engine to stall, especially when running electrical accessories.

Diagnosing Alternator Problems

If you suspect your L200's alternator is failing, it's essential to diagnose the problem accurately. Here's how you can approach it:

1. Visual Inspection: Start by visually inspecting the alternator for any obvious damage, such as cracks, loose wires, or corrosion.
2. Check the Belt: Ensure the alternator belt is in good condition and properly tensioned. A loose or worn belt can cause the alternator to underperform.
3. Battery Voltage Test: Use a multimeter to check the battery voltage with the engine off and running. A healthy battery should read around 12.6 volts with the engine off and 13.5-14.5 volts with the engine running.
4. Alternator Output Test: A mechanic can use a specialized tester to measure the alternator's output and determine if it's producing the correct voltage and amperage.
5. Load Test: A load test applies a load to the alternator to simulate real-world conditions and see if it can maintain the proper voltage output.

If you're not comfortable performing these tests yourself, it's best to take your L200 to a qualified mechanic for diagnosis.

Tools You'll Need:

• New alternator (correct for your L200 model)
• Socket set and wrenches
• Screwdrivers
• Multimeter
• Safety glasses
• Gloves

Steps:

1. Disconnect the Battery: Disconnect the negative battery cable to prevent electrical shock.
2. Locate the Alternator: The alternator is typically located on the front of the engine, driven by a belt.
3. Remove the Belt: Loosen the tensioner pulley and remove the alternator belt.
4. Disconnect Wiring: Disconnect the electrical connectors and wires from the alternator.
5. Remove the Alternator: Unbolt the alternator from its mounting bracket and carefully remove it.
6. Install the New Alternator: Install the new alternator in the reverse order of removal.
7. Connect Wiring: Reconnect the electrical connectors and wires to the alternator.
8. Install the Belt: Reinstall the alternator belt and tighten the tensioner pulley.
9. Reconnect the Battery: Reconnect the negative battery cable.
10. Test the System: Start the engine and use a multimeter to check the battery voltage. It should be in the range of 13.5-14.5 volts.

Choosing the Right Replacement Alternator

When replacing your L200's alternator, it's crucial to choose the right one. Here are some factors to consider:

• Compatibility: Ensure the replacement alternator is compatible with your L200's year, model, and engine type.
• Amperage: Choose an alternator with the same or slightly higher amperage rating as the original. Higher amperage alternators can handle more electrical load.
• Quality: Opt for a reputable brand known for producing high-quality alternators.
• New vs. Remanufactured: You can choose between a new or remanufactured alternator. Remanufactured alternators are typically less expensive but may not last as long as new ones.

Mitsubishi Storm L200 Alternator Replacement Cost

The cost of replacing your L200's alternator can vary depending on several factors:

• Type of Alternator: New alternators are generally more expensive than remanufactured ones.
• Brand: Some brands are more expensive than others.
• Labor Costs: Labor costs can vary depending on the mechanic's hourly rate and the complexity of the job.
• Location: Prices can vary depending on your geographic location.

Generally, you can expect to pay anywhere from $200 to $500 for an alternator replacement, including parts and labor. It's always a good idea to get quotes from several mechanics before making a decision.

Maintaining Your L200 Alternator

To extend the life of your L200's alternator, follow these maintenance tips:

• Regular Inspections: Inspect the alternator and belt regularly for any signs of damage or wear.
• Proper Belt Tension: Ensure the alternator belt is properly tensioned. A loose belt can cause the alternator to work harder and fail prematurely.
• Avoid Overloading: Avoid overloading the electrical system by running too many accessories at once.
• Keep it Clean: Keep the alternator clean and free of dirt and debris.
• Address Problems Early: If you notice any signs of alternator problems, address them promptly to prevent further damage.

Warning Signs of a Failing Alternator

Catching a failing alternator early can save you from being stranded on the side of the road. Be aware of these warning signs:

• Dimming Lights: If your headlights or dashboard lights are dimmer than usual, it could signal a problem with the alternator.
• Slow or No Start: Difficulty starting your L200, or a complete no-start situation, could be due to a weak or failing alternator.
• Unusual Noises: Whining, grinding, or other unusual noises coming from the engine compartment could indicate a failing alternator.
• Battery Light On: The battery warning light on your dashboard illuminating is a clear sign that something is wrong with the charging system, possibly the alternator.
• Electrical Issues: Problems with other electrical components, such as the radio, power windows, or air conditioning, could be related to a failing alternator.

Troubleshooting Common Alternator Issues

Before rushing to replace your alternator, try these troubleshooting steps:

• Check the Battery Connections: Ensure the battery terminals are clean and tightly connected.
• Inspect the Wiring: Look for any damaged or corroded wires connected to the alternator.
• Test the Belt Tension: Make sure the alternator belt is properly tensioned.
• Check the Fuses: Inspect the fuses related to the charging system.

If these steps don't resolve the issue, it's likely the alternator itself is the problem.

Upgrading Your L200 Alternator

If you're running a lot of aftermarket accessories, such as a powerful sound system or off-road lights, you might consider upgrading your L200's alternator to a higher-output model. This will ensure your electrical system can handle the increased load.
