    Great article

    Hey Ben – looks great. I’m curious though – the photo of the Garmin 742 engine display, includes a gauge that reads “55.5 V”.
    Really? Perhaps alternator output, 55 Amps? Not sure what it’s displaying, there….

      That’s for real alternator output voltage, Grant. For one thing, I’ve seen it on other N2K displays, like the Solix 10, but Jim Hebert has the goods:

      “The primary voltage of the E-TEC power generation by its alternator is 55-Volts. The 55-Volt bus runs most of the engine high-current consumption devices. The 55-Volt bus is then regulated down to 12-Volts to provide power for the engine 12-Volt devices and to provide power to external 12-Volt loads. The voltage conversion is accomplished with pulse-width modulation techniques and is very efficient, so …”

        Also, while I don’t have real battery monitoring on Junior, it’s quite useful that Garmin and many other N2K displays can show DC voltage at the unit. So I have it on that main GMI 20 screen along with fuel info, and thus can see battery voltage pretty well when I activate one, or the other, and then how the E-TEC is charging once it’s started. (Also nice to have a dual battery system, which it came with.)
