Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery
- Check for corrosion on terminals; clean with a mixture of baking soda and water if necessary.
- Tighten any loose connections.
Replace Battery (if needed)
- Remove the negative terminal first, followed by the positive terminal.
- Unscrew any hold-down brackets and lift the battery out.
- Place the new battery in the tray and secure it with brackets.
- Reconnect the positive terminal first, then the negative terminal.

3. Starter Motor Inspection and Replacement

Inspect Starter Motor
- Locate the starter motor (typically near the engine/transmission junction).
- Check wiring and connecters for corrosion or damage.
Replace Starter Motor (if necessary)
- Disconnect the battery again as a safety measure.
- Remove electrical connectors from the starter motor.
- Unbolt the starter motor from its mounting.
- Install the new starter motor and secure it with bolts.
- Reconnect electrical connectors.

4. Final Assembly

Reconnect the battery terminals (positive first, then negative).
Ensure all connections are tight and secure.
