Eric, to answer your questoins:

The AEC9005 IBMM/LVWarn product was put on the
market about 2003 time-frame in response to
desires to automatically support the little
auxiliary battery recommended by LightSpeed.
Since detection of an LV condition is primary
to the functionality of the IBMM . . . it was
a simple matter to include a flasher to drive
a LV Warning lamp as well.
Over the 2003 to 2012 market-run, we sold
about 168 completed assemblies and a hand-full
of kits.

The idea was to offer automatic isolation of the
auxiliary ignition battery simultaneously with
annunciation of low voltage.

Z102 is a work in progress. I snatched a
drawing for the AEC9005 to poke into that
slot knowing that the functionality would
require upgrading to accept a signal from
the starter system to keep the contactor
closed during start.
That activity was yet to be accomplished.
The original IBMM did not have a flasher for
driving an LED. It was never produced. Found
the genesis drawing from 1999 which I've modified
to include a lv override input from the starter
push button. Exploit as you see fit.

Yeah, that would make it work as depicted . . .

Correct. The AEC9005 was a stand-alone device that
might have been paired with an external relay that
did not have coil suppression installed. Better to
have TWO such devices than NO such devices!

P.S. the calibration resistors have been adjusted
to raise the L.V. Warn set-point to 13.5 volts.
This will make the finished assembly compatible with
BOTH LiFePO4 and SVLA batteries.
