Secondary ships battery monitor

Hello,
We are upgrading to the ECB ACM this week because we want the built in backup alternator support. We are flying with an EFII electronic ignition system and its bus manager. i see the pin assignments for the two field wires, but am not finding where to input the secondary ships battery. Thanks!

If you are trying to tie the second battery power input into the ACM that's setup is outside the scope what the ACM handles. You would need to combine/isolate the batteries external to the ACM.

If you are trying to measure the second battery then it depends on which EFIS is being used AF-5000 or SkyView with EMS?

Hi,
This is an AF-5000 with the ECB ACM.
Yes, all we are trying to do is measure the second battery. What pin of what connector does this tie into?
Thanks!

Pin 13 on the EFIS Expansion connector is where Volts 2 is on the AF-5000 Series displays. This pin isn't pulled through into the ACM.

Thank you!
