Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to ensure safety.
Tools Required: Socket set, multimeter, battery terminal cleaner.

2. Battery Inspection and Replacement

Inspect Terminals:
- Clean any corrosion on the battery terminals using a battery terminal cleaner.
- Tighten the terminal connections securely.
Battery Replacement (if necessary):
- If the battery voltage is below 12.4 volts after testing, remove the old battery:
  - Disconnect the negative terminal first, followed by the positive terminal.
  - Remove any brackets holding the battery in place.
  - Lift the battery out of the tray carefully.
- Install the new battery:
  - Place the new battery in the tray and secure it with brackets.
  - Connect the positive terminal first, followed by the negative terminal.

3. Starter Inspection and Replacement

Inspect and Test Starter:
- Locate the starter motor (usually near the transmission).
- Check for loose connections or visible damage.
- If the starter is suspected to be faulty, remove it:
  - Disconnect electrical connectors from the starter.
  - Remove the mounting bolts using a socket set.
  - Carefully pull the starter out.
Install New Starter (if necessary):
- Position the new starter in place and secure it with mounting bolts.
- Reconnect the electrical connectors to the starter.

4. Final Checks

Reconnect the negative battery terminal.
Ensure all connections are tight and secure.
