Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Tools Required: Multimeter, socket set, wire brush, battery terminal cleaner.
Sub-steps:
1. Reconnect the battery and measure voltage again. If below 12.4V, proceed to replace the battery.
2. Remove the battery from the vehicle:
  - Unbolt the battery hold-down using a socket set.
  - Disconnect the positive terminal first, followed by the negative terminal.
3. Clean the battery terminals using a wire brush and battery terminal cleaner.
4. Install the new battery:
  - Connect the positive terminal first, followed by the negative terminal.
  - Secure the battery with the hold-down bolt.

3. Starter Replacement (if necessary)

Tools Required: Socket set, torque wrench, screwdrivers.
Sub-steps:
1. Locate the starter motor under the vehicle (usually on the driver's side near the transmission).
2. Disconnect the battery again to ensure safety.
3. Remove the electrical connections from the starter (usually two bolts and a connector).
4. Unbolt the starter from its mounting bracket using the socket set.
5. Install the new starter:
  - Position the starter in place and bolt it securely.
  - Reconnect the electrical connections.

4. Final Checks

Reconnect the negative battery terminal.
Inspect all related connections and ensure everything is tight.
