Solution

1. Preparation

Gather tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Battery Inspection

Examine the battery for signs of corrosion on terminals and clean if necessary using a solution of baking soda and water.
Tighten any loose connections on the battery terminals.
Test the battery voltage with a multimeter; it should read around 12.6 volts when fully charged.

3. Fuse Replacement

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use a fuse puller to remove the fuses related to the malfunctioning systems.
Inspect fuses for continuity using a multimeter and replace any that are blown with a new fuse of the same amperage.

4. Alternator Testing

Reconnect the battery and start the engine.
Use a multimeter to measure the voltage at the battery terminals; it should read between 13.5 to 14.5 volts with the engine running.
If the reading is below this range, consider replacing the alternator.

5. Ground Connection Check

Identify and inspect all ground points in the vehicle, particularly those connected to the battery and electrical components.
Clean any corroded ground connections and ensure they are tight and secure.

6. Wiring Inspection

Visually inspect wiring harnesses for any signs of wear or damage.
Repair or replace any damaged wiring, ensuring proper insulation is restored.
