Gets you a fancier box, too.
It's just a round number convenient for the test.
Depending on what size pulley's on the alternator (probably 2½"), that's roughly right.
Otherwise known as 2400 engine RPM, if your alternator pulley is 2½" and your crank pulley is 6¼" (which sounds small to me, think it's closer to 7", which would mean alternator 6krpm is about engine 2140 rpm).
That is true. I forgot all about that winding-varnish; it's been two decades since I messed with a new points-type regulator.
The dash gauge won't read anything meaningful/reliable if you do the wire mod.
No reason why not.

I was hoping the answer would be better like the dash amp would indicate whether the system was charging or whether a discharge is occurring.....call it a charge indicator light?

If the dash amp gauge is in the higher resistance circuit in parallel with the underhood amp gauge in a much lower resistance circuit then would there be a measureable lower current flow in the dash amp circuit when the alternator was successfully charging away?

If bad things were detected a look under the hood at the underhood amp gauge would be in order to see if a melt down was in progress somewhere?

Should I investigate the Megafuse thing in the article referenced?

Nope. You won't get a meaningful indication on the dash gauge. You can convert it to a voltmeter very cleanly without any hacks. How much it costs depends on whether you do the work yourself or have it done for you. Look at this-- stealth
conversion of stock ammeter to voltmeter for "it must've come that way from the factory!" appearance; that's the primo, higher-cost option. People have also successfully bought an inexpensive aftermarket voltmeter, torn it apart, and retrofitted it to a stock dash cluster with clean results. See here and here, for example.
Which Megafuse in which article?

It's got the external shunt info in your July 12, 2012 response called "Post subject".
