The EarthX batteries provide a discrete output for each pulse, which is a ground signal (active low). However, EarthX batteries 100 series, such as the ETX 900, only have three indications - slow flashing (five seconds on, five seconds off), short flashing 2 seconds on, 2 seconds off) or on solid.
If you have it connected to a discrete input, then the fault indication on the EFIS should come on or off and repeat until the fault clears per the table.
To understand the fault, you need to compare battery voltage against slow, short flashing or on solid.
But either way, it's just a discrete input and should work as if it were pulsing an LED light.
I've tested this on my G3X and it indicates correctly. BTW, there is a fault LED on the battery itself, so if you're testing, you can compare what the battery LED is indicating vs the EFIS.

- RV12, N975G, "The Commuter"...many great hours and happy landings so far.
- Several others that are now just great memories for me.
