Solution

1. Preparation

Gather tools: multimeter, socket set, wrenches, battery terminal cleaner, and safety goggles.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Connections
- Clean any corrosion from battery terminals using a battery terminal cleaner.
- Tighten the connections securely.
Test Battery Voltage
- Reconnect the battery.
- Use a multimeter to measure the voltage. If below 12.4 volts, consider replacing the battery.
Replace Battery (if necessary)
- Disconnect the negative terminal followed by the positive terminal.
- Remove the battery hold-down bracket.
- Carefully lift the battery out of the tray.
- Place the new battery in the tray, ensuring correct terminal orientation.
- Reinstall the hold-down bracket and connect the positive terminal first, then the negative terminal.

3. Starter Motor Inspection and Replacement

Inspect Starter Connections
- Locate the starter motor (typically beneath the engine).
- Check for loose connections or damaged wires; repair as necessary.
Test Starter Motor
- If connections are secure and the battery is good, test the starter by applying direct power from the battery using jumper cables.
- If the starter does not engage, it may need replacement.
Replace Starter Motor (if necessary)
- Disconnect the battery again.
- Remove the starter motor bolts and electrical connections.
- Install the new starter motor in reverse order, ensuring all connections are secure.
