Dual battery system voltages

[dnhowald]

Have a dual battery electrical system. How can I read both battery voltages on the EMS. ALso can I hook the EMS audio out and the EFIS audio out to the same terminal on the volume control pot.

The EMS can only display one voltage. There's no way to display a second source. The EFIS can display two if you have an EFIS.

You can hook the EFIS and EMS audio wires together and then run them to the volume control pot. They are identical circuits so they will have identical volumes.
