why does my Tesla Outback's dashboard light keep flickering?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is off.
• Disconnect the negative terminal of the battery.

2. Inspect Battery and Connections

• Check the battery terminals for corrosion; clean with a wire brush if needed.
• Ensure that the battery connections are tight and secure.
• Reconnect the battery and check if the flickering persists.

3. Check Fuses

• Locate the fuse box, typically found under the dashboard or in the engine bay.
• Refer to the owner's manual for the specific fuse related to the dashboard lights.
• Remove the fuse and inspect it; replace if blown with an equivalent amperage fuse.

4. Inspect Wiring and Connectors

• Remove the dashboard cover (if necessary) to access wiring.
• Visually inspect all wiring for frays, breaks, or corrosion.
• Clean any connectors with electronic cleaner and ensure they are securely connected.

5. Test Alternator Output

• Use a multimeter to measure the voltage at the battery while the engine is running.
• Voltage should read between 13.7 to 14.7 volts; if lower, the alternator may need replacing.
