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. GRT sells the Key100 sensor as CS-01 ($89, includes cable though)
Shunts need 1A inline fuses for each of the two current sensor connectors, Hall effect sensors do not.
The Key100 sensor doesn't really have a proper Molex connector, rather it has 3 gold pins that are cut off a wire wrap pin header strip plus a plastic glued on that makes it asymmetric for Molex connectors.
Somewhat compatible connector housing (needs some mods on the sensor):
- Molex 0022011032 connector housing @ Digikey (in stock)
- Molex 0022011032 connector housing @ RS (no shipment date)
22 AWG Pins
- 22 AWG gold plated 08550102 pins for Molex connector @Digikey (in stock)
- 22 AWG gold plated 08550102 pins for Molex @ RS (backordered)
