Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent accidental short circuits.

2. Inspect and Clean Battery Connections

Remove the positive (+) and negative (-) battery terminals.
Clean any corrosion from the terminals and battery posts using a wire brush and baking soda solution.
Reattach the battery terminals securely, starting with the positive terminal first.

3. Test and Replace the Battery (if necessary)

If the battery voltage was below 12.4 volts, proceed to replace it.
Remove the battery hold-down bracket using a socket set.
Carefully lift the battery out of the tray.
Install the new battery in reverse order, ensuring correct polarity.

4. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or hood).
Identify the starter and accessory fuses.
Remove any blown fuses and replace them with fuses of the same amperage.

5. Inspect and Test the Starter Motor

Locate the starter motor (usually near the engine block).
Test the starter by using a multimeter to check for voltage at the starter terminal when the ignition key is turned.
If the starter is faulty, remove it by disconnecting the electrical connections and bolts, then replace it with a new starter.
