Electronic Noise Filters
The interference or electronic "noise" generated by alternators, ignition systems, motors, etc., can render a vessel or vehicle's radio or other electronic equipment virtually useless. This interference takes the form of popping or static on radios or audio gear and garbled images or "hash" 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. Installation varies with equipment. The PC-10 installation is in the (+) and (-) power leads close to affected equipment. Location for 150-A installation is in the alternator output lead.
