Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure vehicle is in a safe area, and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion from terminals using a wire brush.
- Tighten the terminal connections.
Test Battery Condition
- Reconnect the battery and perform a load test.
- If the battery is weak (below 12.4 volts under load), replace it with a new one.
- Tools Required: Battery tester, wire brush.
- Parts Required: Replacement battery (if needed).

3. Starter Motor Inspection

Access Starter Motor
- Raise the vehicle using a jack and secure it with jack stands.
- Locate the starter motor, usually near the engine block.
Inspect and Test Starter Motor
- Visually inspect the starter for damage or loose connections.
