Current Sensors

Instead of using resistor shunts to measure battery or alternator currents, one can also use Hall effect sensors that do not necessitate to cut the cable and run the current through a shunt (more failure points). Garmin recommends the Amploc Key100 sensor. Reportedly, Dynon also recommends it.
Shunts need 1A inline fuses for each of the cables, Hall effect sensors do not.
