That works!

Gentlemen: planning a Z-12 -based dual alternator and single battery but
with both alternator outputs paralleled into the 60A shunt and eliminating
the Hall effect sensor for the standby alternator B-lead. The panel
builder is politely suggesting I will be happier if I keep two independent
current monitoring channels in place. Please review my missive to him and
see if I am overlooking anything. Thanks!
>>>>>>>>>>
Plan (1) - Wired using one each Shunt and Hall channels: 60A alternator is
regulated at 14.4V. Adequate for all possible loads, it always outputs
through the shunt and its current shows on the EFIS in that channel. 20A
standby alternator is regulated at 13.0V. The Hall effect sensor reads
zero current on the EFIS basically forever - not a very informative data
channel on the EFIS. The day the primary alternator breaks a belt, the
shunt current drops to zero, the Hall sensor shows alternator output from
the standby, and the bus voltage drops quickly to ~13V as the standby
alternator takes the load.
Plan (2) - Both alternators feeding through the shunt in parallel, no Hall
sensor: Shunt shows combined output current from both alternators, which
is always 100% primary alternator, 0% from standby (because it's regulated
to 13 volts into a bus that's already at 14.4V). If the primary alternator
ever fails, then the shunt current reading is 100% from the standby
alternator. The bus voltage drops to ~13V which is the immediate clue the
primary alternator is off-line.
This same behavior allows testing the alternators separately at any time
the engine is running by switching off their field supplies one at a time
and observing: current in scenario (1) or bus voltage in scenario (2).
The shunt in (2) reads system loads regardless of which alternator is
doing the work. The Hall in (1) reads zero except when a failure or test
occurs. This just means the pilot has to look at a new EFIS channel to see
current if the main fails.
In Plan (1), either the shunt or the Hall will always read zero. In plan
(2), the shunt will always read current from one or the other alternator,
but never both - and bus voltage is the indicator of which alternator is
doing the work.
Not sure a Hall sensor that reads zero in normal operations and only tells
me current that the shunt in (2) would show me just as well in a failure
scenario is worth buying and wiring in.
