About Noise Filters:

The interference or electronic "noise" generated by alternators can render a vehicle or vessel's radio or other electronic equipment virtually useless or annoying. This interference takes the form of a whining pitch in radios, audio sound systems or garbled images "interference lines" on video displays.

These specialized filters can be used singly or in combination to attenuate conducted line noise, either at the affected equipment or at the noise source.  We suggest you install in series wth the alternator output lead which feeds the battery.  Neutral lead (and shielded housing) connects to alternator case near engine block.  Install as close to alternator as possible however do not install on the engine itself.
