Solution

1. Preparation

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

2. Inspect Battery and Connections

Sub-steps:
- Remove the battery terminals, starting with the negative terminal.
- Clean the battery terminals and cable ends with a wire brush.
- Reconnect the terminals securely, ensuring a tight fit.

3. Test Alternator Output

Sub-steps:
- Reconnect the battery and start the engine.
- Use a multimeter to measure voltage at the battery terminals; it should read between 13.7 to 14.7 volts.
- If the voltage is below this range, the alternator may need replacement.

4. Check Fuses

Sub-steps:
- Locate the fuse box (typically under the dashboard or in the engine compartment).
- Identify the fuse associated with dashboard lighting and inspect it.
- Replace any blown fuses with new ones of the same amperage.
