My idea or question was that if I put capacitors on each power feed to each instrument, would this eliminate it as a potential source of trouble? What do you consider to be a "good" alternator filter? You really only have to supress the noise if you actually have a generator making it. I would install the equipment, and then move the boat out, away from any yard or industrial like setting, before testing for RFI. One of the things I have found over the years, is that most shipyards are VERY NOISY PLACES, and you can't really find locally generated noise, because it is being masked by the Yards noises. Back in the day, we used to do most of the testing while the boat was out on SeaTrials in Puget Sound, well away from the yards and docks. Numar builds a very good set of Alternator Filters, that we have used for years. I like their 80Amp version, myself, but the 160Amp version works well for those BIG Alternators.
