Dead Battery
A dead battery is one of the most common electrical issues faced by Subaru Outback owners. This can be caused by leaving lights on, a faulty battery, or an issue with the charging system.
Troubleshooting Tips for a Dead Battery
- Check for any lights that may have been left on.

Faulty Alternator
The alternator charges the battery while the engine is running. A faulty alternator can lead to battery drain and electrical system failures.
Troubleshooting Tips for a Faulty Alternator
- Listen for unusual noises from the alternator area.
- Check the alternator belt for wear or looseness.
- Use a multimeter to test the voltage output; it should be between 13.7 and 14.7 volts.
- Look for warning lights on the dashboard indicating charging system issues.
- If necessary, have the alternator tested at an auto parts store.
Malfunctioning Starter
A malfunctioning starter can prevent the engine from starting. Symptoms include clicking noises or a complete lack of response when turning the key.
Troubleshooting Tips for a Malfunctioning Starter
- Listen for a clicking sound when trying to start the car.
- Check the battery voltage; a weak battery can affect the starter.
- Inspect the starter connections for corrosion or loose wires.
- Test the starter relay by swapping it with another relay of the same type.
- If the starter is suspected to be faulty, consider replacing it.
Electrical Shorts
Electrical shorts can cause various electrical components to malfunction. This can lead to blown fuses or erratic behavior of electrical systems.
Troubleshooting Tips for Electrical Shorts
- Inspect fuses for any that are blown and replace them as needed.
- Check wiring harnesses for frayed or damaged wires.
- Look for signs of moisture or corrosion in electrical connectors.
- Use a multimeter to test for continuity in suspect circuits.
- If a short is suspected, consider consulting a professional mechanic.
