What is alternator filter?
Newmar 150-A Alternator Filter. Noise Filters. The interference or electronic "noise" generated by alternators, ignition systems, motors, etc., can render a vehicle or vessel's radio or other electronic equipment virtually useless.
What does a noise filter do on a car?
A car audio noise filter is also known as a ground loop isolator. This device blocks high-frequency current coming from your car electrics into your car audio system. The removal of this high-frequency interference will stop all unwanted whining sounds and interference.29 May 2021
How do I stop my alternator from Whineing through my speakers?

How can ground looping be prevented?
- DON'T SHARE GROUNDS.
- MINIMIZE LOOP AREA WITH TWISTED PAIR WIRING.
- DON'T GROUND REMOTE SENSORS.
- USE SHIELDED WIRE GROUNDED ONLY TO THE CONTROLLER.
What causes ground loop noise?
Ground loops can happen when multiple devices are connected to a common ground via different paths. When a ground loop occurs, the cable's ground conductor (often the shield) ends up carrying both the audio ground and hum/noise caused by power flowing through the ground connection.2 Apr 2019
