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

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the ignition is turned off.
• Gather tools: multimeter, battery tester, socket set, and cleaning supplies.

2. Inspect and Clean Battery Connections

• Sub-steps:
  1. Disconnect the negative terminal of the battery to prevent short circuits.
  2. Inspect the battery terminals for corrosion; use a wire brush to clean them if necessary.
  3. Reconnect the battery terminals securely, starting with the positive terminal followed by the negative.

3. Test and Replace the Battery (if necessary)

• Sub-steps:
  1. Use a multimeter to check the battery voltage; it should read around 12.6 volts for a fully charged battery.
  2. If the voltage is below 12.4 volts, charge the battery using a suitable charger.
  3. If the battery fails the load test or does not hold a charge, replace it with a new battery of the same specifications.

4. Inspect and Test the Starter Motor

• Sub-steps:
  1. Locate the starter motor; it is typically found near the engine block.
  2. Check the wiring harness connected to the starter for any damage or loose connections.
  3. Use a multimeter to test for voltage at the starter terminal while someone turns the ignition to the start position.
  4. If no voltage is present, the issue may be with the ignition switch or relay. If voltage is present but the starter does not engage, replace the starter motor.
