Solution

1. Preparation

Gather tools: socket set, OBD-II scanner, multimeter, flashlight, rags.
Ensure the engine is cool to prevent burns.
Disconnect the battery before working on electrical components.

2. Inspect and Replace Components

Inspect Wiring Harness
- Check all wiring harnesses for signs of damage or melting.
- Repair or replace any damaged wires as necessary.
Inspect Belts and Hoses
- Remove the engine cover if applicable.
- Examine belts for wear, cracking, or burning.
- Replace any damaged belts (torque specifications as per manufacturer).
- Inspect hoses for leaks or signs of melting; replace if necessary.
Fluid Check and Top Up
- Remove the oil filler cap and check oil condition; replace if burnt or contaminated.
- Inspect the coolant reservoir; top up with manufacturer-recommended coolant if low.

3. Electrical System Check

Test Alternator and Battery
- Use a multimeter to check the battery voltage; it should be around 12.6 volts with the engine off.
- Start the vehicle and measure voltage again; it should be between 13.7 to 14.7 volts. Replace alternator if out of range.

4. Reassemble and Clean

Reinstall any removed components or covers.
Clean any spilled fluids with rags to prevent future smells.
Reconnect the battery.
