my Tesla Outback won't start just clicks what should I check

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, and a wrench set.
• Ensure the vehicle is in Park or Neutral and the parking brake is engaged.
• Disconnect the negative battery terminal to ensure safety.

2. Battery Check

• 1.1: Reconnect the battery terminal and use a multimeter to measure the voltage. If it reads below 12.4V, charge or replace the battery.
• 1.2: Inspect and clean the battery terminals. Remove any corrosion using a wire brush and a mixture of baking soda and water.

3. Starter Motor Inspection

• 2.1: If the battery is good, check the starter motor. Locate the starter (usually at the rear of the engine).
• 2.2: Disconnect the starter motor's electrical connections.
• 2.3: Use jumper cables to apply direct power to the starter; if it engages, it needs replacement.

4. Wiring and Fuse Check

• 3.1: Inspect all relevant fuses using the vehicle’s fuse box diagram.
• 3.2: Replace any blown fuses with the appropriate rating.
• 3.3: Check the wiring harness connected to the starter and ignition systems for any signs of wear or damage.

5. Reassembly and Final Checks

• 4.1: Reconnect all components and terminals securely.
• 4.2: Reconnect the negative battery terminal.
• 4.3: Attempt to start the vehicle again.
