No amps reading on #2 alternator

[Tom]

Ron I am not familiar with the dual alternator setup on the PTs. But I am
willing to learn . Cant figure out why they would want to run the wire
thru a circuit breaker and/or a switch after the shunt? Doesnt the output
of both alternators go thru the same shunt?
