Solution

1. Preparation

Gather tools: socket set, multimeter, jumper cables, and safety glasses.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Disconnect Battery:
- Use a socket wrench to disconnect the negative battery terminal first, followed by the positive terminal.
Clean Terminals:
- Inspect and clean battery terminals with a wire brush to remove corrosion.
Test Battery:
- Reconnect the battery temporarily and test voltage again. If below 12.4 volts, replace the battery.
Install New Battery:
- If replacement is needed, connect the new battery by attaching the positive terminal first, then the negative terminal.

3. Starter Motor Inspection

Access Starter Motor:
- Depending on the model, locate the starter motor; may require removal of engine covers.
Check Connections:
- Inspect the electrical connections to the starter for tightness and signs of wear.
Test Starter with Jumper Cables:
- Connect jumper cables directly to the starter motor to bypass the ignition circuit. If the starter engages, it may need replacement.

4. Replace Starter Motor (if necessary)

Remove Starter Motor:
- Unbolt the starter motor from its mounting bracket using a socket set, noting the orientation of any wiring.
Install New Starter Motor:
- Position the new starter motor in place and secure it with bolts to the mounting bracket.
Reconnect Wiring:
- Attach electrical connections to the starter, ensuring they are secure.
