Very weird question: exciter wire for alternator

[jumpsoffrock]

I'm working on a 60's GM vehicle.

Like many of them, a 4ga Black wire goes from the battery to the starter, and from there a 10ga Red wire feeds the main fuseblock in the interior.

I would call that a "main distribution point". No?

When I was learning to wire a 3-wire Alternator setup, i was advised that if you have a distribution point nearby in the engine bay, connect the exciter wire to that distribution point, so when you are drawing a load with your accessories, your alternator is taking a reading of the voltage drop AT THAT distribution point and will therefore do a more precise job of maintaining proper voltage.

Would it be responsible to send the alternator exciter wire to the "distribution point" at the starter solenoid? or is that trying too hard?





Why I posted this thread to start with: I want to add a small auxiliary fuse panel in the engine bay--this aux fuse panel may experience a few medium/high draw accessories--and was going to power it with a 10ga wire, and was trying to figure a place to take power from, if not the battery. So then I thought, connect the aux-fuse panel to the distribution point where the alternator senses voltage.

But then I got confused, because I asked myself, "which is more important, the main fuse panel draw, or the draw from my aux fuse panel?"


then I thought, why don't I just centre the draw at the same point? Connect the 10ga for the aux fuse panel to the starter solenoid, then connect the alt sense wire to that same distribution block...


Whad'ya think?

(OT: I am also strongly considering installing a Ford starter solenoid, and using that as my base of operations)
