Modern Chrysler vehicles are packed with advanced electronics—from infotainment systems to engine control modules. When something goes wrong, pinpointing the issue requires more than guesswork. That’s where SouthWest CDJR, your local Chrysler dealership in Cleburne, comes in. With factory-trained technicians and Mopar-certified diagnostic tools, we can quickly identify and resolve electrical problems to keep your vehicle running smoothly.

Here are five key electrical diagnostics you can expect from a certified Chrysler service center:

Certified Chrysler Service Center at SouthWest CDJR

1. Battery Health & Load Testing

A dead battery is easy to spot—but underlying battery issues often go unnoticed. Chrysler technicians perform:

  • Voltage checks to ensure the battery holds a proper charge (12.6V when idle, 13.7–14.7V when running)
  • Load tests to assess how the battery performs under stress
  • Visual inspections for corrosion or loose terminals

If your battery is below 80% capacity or shows signs of parasitic drain, it may need replacement or further testing.

2. Alternator & Charging System Diagnostics

The alternator powers your vehicle’s electrical systems and recharges the battery while driving. Signs of a failing alternator include:

  • Dim headlights
  • Flickering dashboard lights
  • Frequent battery drain

Technicians use multimeters and scan tools to check voltage output and inspect the serpentine belt, voltage regulator, and wiring.

3. Fuse & Circuit Troubleshooting

If a single electrical component—like your radio or power windows—stops working, a blown fuse may be the culprit. Chrysler service centers:

  • Locate and replace blown fuses
  • Diagnose root causes like power surges or faulty wiring
  • Inspect fuse boxes for damage or corrosion

Fuses are inexpensive, but repeated failures may signal deeper electrical issues.

4. Starter Motor & Relay Testing

The starter motor receives power from the battery to crank the engine. Common symptoms of failure include:

  • Clicking sounds when turning the key
  • Slow or no engine cranking
  • Smoke or burning smells from the engine bay

Technicians test the starter solenoid, ignition switch, and wiring using multimeters and voltage drop tests.

5. Ignition Coil & Spark Plug Diagnostics

Ignition coils send voltage to spark plugs, which ignite the fuel-air mixture in your engine. Worn coils or plugs can cause:

  • Misfires
  • Poor fuel economy
  • Rough idling

Chrysler dealerships inspect coil packs, test spark plug gaps (typically 0.043″ for 3.6L Pentastar engines), and replace components as needed.
