Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe environment with enough space to work.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean any corrosion present at the battery terminals using a wire brush.
- Tighten the battery connections to ensure a solid contact.
Replace Battery (if necessary):
- Remove the old battery by unfastening the hold-down bracket and disconnecting the positive terminal first, followed by the negative terminal.
- Install the new battery by connecting the positive terminal first, followed by the negative terminal, and secure it with the hold-down bracket.

3. Starter Motor Testing and Replacement

Testing Starter Motor:
- Locate the starter motor (typically found near the transmission bell housing).
- Use jumper cables to connect the starter motor directly to the battery to see if it engages.
Replace Starter Motor (if necessary):
- Disconnect wiring harness from the starter motor.
- Remove bolts securing the starter motor and carefully take it out.
- Install the new starter motor by reversing the removal process and ensure all connections are secure.

4. Reconnect Battery and Final Checks

Reconnect the negative battery terminal.
Start the vehicle to check if it cranks properly.
Inspect for any abnormal sounds or electrical issues.
