Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, battery terminal cleaner, jumper cables.
Safety: Disconnect the battery negative terminal before working on the electrical system.

2. Battery Replacement (if testing indicates low voltage)

Remove the old battery:
- Use a socket set to remove the battery hold-down bracket.
- Disconnect the negative terminal first, followed by the positive terminal.
- Carefully lift the battery out of the tray.
Install the new battery:
- Place the new battery in the tray and secure it with the hold-down bracket.
- Connect the positive terminal first, then the negative terminal.
- Tighten the connections to ensure a solid contact.

3. Starter Replacement (if the starter is determined to be faulty)

Remove the starter:
- Disconnect the negative battery terminal to prevent short circuits.
- Locate the starter motor, typically found near the transmission.
- Remove the electrical connections from the starter (noting their positions).
- Unbolt the starter from the engine block using a socket set.
Install the new starter:
- Position the new starter in place and secure it with bolts.
- Reconnect the electrical connections, ensuring they are tight.
- Reconnect the negative battery terminal.
