Given this, is sensing location really a distinguishing feature?
On the ARS-5 the regulator
power and sense are the same wire, red. The brown is simply ignition/on....
On the MC-614 the sense wire has zero current
on it so it is a pure voltage sensing wire. It does not power the regulator
AND sense voltage at the same time like the ARS-5....
For the best charging
performance sensing the bank is paramount. However, if sensing the actual battery bank the charge current
MUST also feed directly to that bank. You can't sense a bank if alt current passes through a battery switch than can "charge direct" or switch which bank gets charged........
