Solution

1. Preparation

Gather tools: Multimeter, fuse puller, screwdriver set, wire connectors, electrical tape.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and locate the radio fuse.
Use a fuse puller to remove the fuse and visually inspect it for continuity.
- If the fuse is blown:
  - Replace it with a new fuse of the same amperage (typically 10A or 15A, check the fuse box diagram).

3. Check Wiring Connections

Remove the radio from the dashboard using a screwdriver to access the wiring harness.
Inspect the wiring harness for any loose connections or frayed wires.
If any wires are damaged, repair them by stripping the ends and using wire connectors or electrical tape to resecure.

4. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Turn the ignition switch to the "ON" position and test the radio to see if it powers on.
