Re: GTV-6 or Milano alternator, part 2

[GLewis4457@domain.elided]

This evening I had a chance to put a voltmeter on the charging system of my 
GTV-6.

At idle (800-1000rpm), I measured 12.46v, at the battery.  If I held the 
accelerator to 3000 the charge would slowly increase to almost 13v.  With the 
radio and a/c on it dropped to 12.14 volts.  Even with the increased volts at 
higher RPM's the alternator, AND the ox sensor light next to it, stay light 
although they get dimmer.  It did not do this at all before the sudden 
stalling and stopping of the car in traffic yesterday.  As I said in my 
earlier post I replaced the battery with a known good one and charged it 
fully.  Motor spins nicely now and car starts almost instantly, but the 
alternator light concerns me.  Does the GTV-6 alternator have an internal or 
external voltage regulator?  Should I take it out and have it checked?  How 
much trouble is this or should I get the checkbook out?  This is all new to 
me.  I am used to the Alfetta and the 4 cyl. but know nothing about the v-6.  
I guess I am going to start learning.  All help is appreciated.
