Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and goggles.

2. Battery Terminal Cleaning

Tools Required: Wire brush, battery terminal cleaner, wrench
Sub-steps:
1. Disconnect the negative (-) terminal first, followed by the positive (+) terminal.
2. Use a wire brush to clean any corrosion from the battery terminals and cable connectors.
3. Reconnect the positive (+) terminal first, followed by the negative (-) terminal securely.

3. Battery Replacement (if necessary)

Tools Required: Wrench, battery strap, safety gloves
Sub-steps:
1. If the battery is confirmed dead, remove the old battery by loosening the hold-down strap and disconnecting both terminals.
2. Lift out the old battery carefully.
3. Place the new battery into the battery tray and secure it with the hold-down strap.
4. Connect the positive (+) terminal first, followed by the negative (-) terminal.

4. Alternator Check (if applicable)

Tools Required: Multimeter
Sub-steps:
1. Start the engine and let it idle.
2. Use a multimeter to measure voltage at the battery terminals; it should read between 13.7 and 14.7 volts.
3. If the voltage is below this range, the alternator may need replacement.
