Solution

1. Preparation

Gather tools: multimeter, jumper cables, socket set, and a torque wrench.
Ensure safety by wearing gloves and safety glasses.

2. Battery Inspection and Replacement

Check Battery Condition:
- Use a multimeter to measure the battery voltage.
- If the voltage is below 12.4 volts, proceed to jump start the battery.
Jump Start the Battery:
- Connect jumper cables to the dead battery and a working battery.
- Start the working vehicle and let it charge the dead battery for a few minutes.
- Attempt to start the Tesla Outback.
Replace Battery if Necessary:
- If the vehicle does not start after jump-starting, disconnect the jumper cables.
- Remove the battery terminals (negative first, then positive).
- Unscrew the mounting bracket and remove the old battery.
- Install the new battery, ensuring correct polarity and secure the terminals.

3. Starter Motor Inspection and Replacement

Test Starter Motor:
- Disconnect the battery before working on the starter.
- Locate the starter motor and check connections for tightness and corrosion.
- Use a multimeter to check for voltage at the starter while someone turns the ignition key.
Replace Starter Motor:
- If no voltage is detected, or if the starter motor is faulty, remove it by unscrewing the mounting bolts.
- Install the new starter motor and tighten to the manufacturer's specified torque.
- Reconnect the battery.
