G3X voltage reading

[Webb]

If the power source is battery only (engine not running), should the voltage displayed on the G3X be zero since there isn’t an alternator running or display the battery voltage?

I guess it might depend on where you are measuring the voltage, but I can't really figure out any way that the voltage should be reading at zero. In other words, I think you have a bad sensor.

Typically, you'd see about 12V when running on battery and about 14V when the alternator is running.

I think the voltage is sensed off a pin the GEA24. The alternator is a separate sensor.

This will certainly happen if there is 0 V on the input you have configured to read voltage. More information about your installation would be required to offer specific advice.

There is no external sensor for voltage.
If the sensing wire, for some reason is not connected or the input has not been configured then 0V will be displayed.
In configuration mode, check that the GEA24 Voltage setting is set to other than "None". "Main bus" would be logical in most installations.

Good luck

issue Fixed. Checked schematics and the input is on volts 2 from the IBBS. Changed the configuration from Volts 1 to 2 and turned on IBBS.
Thanks for the clue on where to look.
