Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park or neutral with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Check and Replacement

Inspect the Battery:
- Clean any corrosion from battery terminals using a wire brush and a mixture of baking soda and water.
- Tighten the battery terminals securely.
Replace the Battery if Necessary:
- If the battery voltage is low or fails the load test, remove the old battery:
  - Disconnect the negative terminal first, then the positive terminal.
  - Remove any retaining brackets and lift the battery out.
- Install the new battery:
  - Place the new battery in the tray.
  - Connect the positive terminal first, then the negative terminal.
  - Secure the battery with the retaining brackets.

3. Starter Motor Inspection

Visual Inspection:
- Locate the starter motor (typically found near the transmission bell housing).
- Inspect the wiring and connections for damage or corrosion.
Test the Starter:
- If the connections are intact, use a multimeter to check for voltage at the starter terminal when the ignition key is turned.
- If no voltage is present, further diagnose the ignition switch.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Attempt to start the vehicle to verify the issue is resolved.
