3. Operation
Once correctly installed, the Keenso 12V DC Power Relay Capacitor Filter Rectifier operates automatically. It filters and stabilizes the 12V DC power supplied to your rear view camera, ensuring a consistent and clear video feed. This prevents visual distortions such as flickering, rolling lines, or a completely black screen, which are often caused by unstable power from the vehicle's reversing light circuit.

4. Maintenance
The Keenso Power Relay Capacitor Filter Rectifier is designed for durability and requires minimal maintenance. To ensure optimal performance and longevity:
- Keep Dry: Avoid exposing the device to excessive moisture or water.
- Inspect Connections: Periodically check all wiring connections to ensure they remain secure and free from corrosion.
- Clean Gently: If necessary, gently wipe the exterior with a dry, soft cloth. Do not use harsh chemicals or abrasive cleaners.
- Avoid Physical Damage: Ensure the device is installed in a location where it is protected from physical impact or crushing.
5. Troubleshooting
If you experience issues with your rear view camera after installing the rectifier, consider the following troubleshooting steps:
- No Image or Black Screen:
- Verify that all input and output wires are correctly connected according to the wiring diagram (Image 2, Image 3).
- Ensure the reversing light is receiving power when reverse gear is engaged.
- Check the camera's power connection to the rectifier's output.
- Flickering or Unstable Image:
- Confirm that the rectifier's input wires are securely connected to the reversing light's positive and negative poles. Loose connections can cause instability.
- Ensure the camera's power and ground connections from the rectifier are solid.
- In some cases, interference can still occur if the vehicle's electrical system has significant noise. While the rectifier is designed to mitigate this, extreme cases might require further electrical system diagnosis.
- Incorrect Polarity: Double-check that the positive and negative wires are connected to their respective poles. Incorrect polarity can prevent the device from functioning.
- Device Damage: Inspect the rectifier for any visible signs of damage. If damage is present, the unit may need replacement.
