The EMU-1 can operate between 9 and 35 VDC and will typically use 25mA at 12 VDC.
If the engine gauges are to remain in-circuit, the EMU-1 must be powered from exactly the same power supply as the gauges otherwise the EMU-1 measurements will not being accurate. The EMU-1 gauge ground and the EMU-1 power ground must be common to prevent ground loops. Check that if the instrument gauge panel includes a reverse protection diode between the power supply and the actual gauge supply connection, the EMU-1 is correctly powered from the gauge supply connection.
