- Hazard Lights Not Working: Check the hazard flasher unit and switch connections.
2. Tips for Working with Electrical Systems
- Disconnect the Battery: Always disconnect the battery before working on any electrical system.
- Use a Multimeter: A multimeter is essential for testing voltage, continuity, and resistance.
- Clean Connections: Clean any corroded connections with a wire brush and electrical contact cleaner.
- Use Proper Wiring: Use automotive-grade wiring and connectors for repairs.
- Document Your Work: Take photos and notes to help you remember how things were connected.
