Hello :-)
I have an MGL Enigma EFIS and will put in a backup battery. In regular operation,
both the main and backup battery are to be wired to the EFIS. The Enigma automatically
switches to backup when it senses a main battery low voltage.
I was thinking of maybe some wiring of a 2-10 that would do the following:
Down position: main buss to EFIS.
Middle position: backup battery to EFIS (for backup battery check)
Up position: both batteries to EFIS.
Or maybe just a two position switch, one position would be for both batteries,
the other just to the backup. The backup check position could be a momentary on,
I suppose, that just takes the main battery offline. Hold it in this position
and see if the EFIS still works, then release.
