Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set), and a wiring diagram if available.
Ensure the vehicle is parked on a flat surface, and the ignition is off.

2. Battery and Connections

Step 1: Disconnect the negative battery terminal using a wrench.
Step 2: Clean the battery terminals with a wire brush and apply a corrosion inhibitor.
Step 3: Inspect and tighten all connections on the battery and ground points.

3. Fuses and Wiring Inspection

Step 1: Remove the fuse box cover and check each fuse visually or test with a multimeter.
Step 2: Replace any blown fuses with the same amperage rating.
Step 3: Using the wiring diagram, trace wires for signs of wear or damage, securing any loose connections.

4. Alternator Testing

Step 1: Reconnect the battery terminals.
Step 2: Start the engine and use the multimeter to check the voltage at the battery; it should read between 13.5 to 14.5 volts.
Step 3: If the voltage is low, replace the alternator.
