I want to keep the DC away from the (aluminum) boat.Thanks, Michael Porter Michael Porter Marine Design mporter at mp-marine dot com www.mp-marine.com I did look into capacitor grounding some time ago and whoever I talked to said shove a bunch of capacitors in parallel into the system. This was based on having enough parallel capacitors to carry the signal amperage as well as voltage. I asked whether impedance was important and was told "probably not as long as you have enough capacitance." Larry will probably have more to say on the subject.... Cheers, Bruce |
