- Inspection: Periodically check wiring connections for tightness and signs of wear or corrosion. Ensure the fuse is intact and correctly rated.
- Fuse Replacement: If lights fail to turn on or dim, check the 10A fuse on the +12V line. Replace with a fuse of the same rating if blown.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn ON. | No power to the switch. Blown fuse. Incorrect wiring. Faulty light bulb/fixture. | Check RV's main power supply. Inspect and replace the 10A fuse if necessary. Verify all wiring connections (Red, Black, White) are secure and correct. Test lights with a known working power source. |
| Lights do not dim. | Lights are not dimmable. Incorrect wiring. Faulty dimmer mechanism. | Ensure connected lights are compatible with dimming (e.g., dimmable LEDs). Verify the White (PWM V+) wire is correctly connected to the light's dimming input. Contact customer support if the dimmer slider has no effect on dimmable lights. |
| Lights flicker or hum when dimmed. | Incompatible lights. Loose connections. | Some non-dimmable or low-quality LED lights may flicker. Ensure dimmable lights are used. Check all wiring connections for tightness. |
