[alfa] GTV-6 voltage drop

[Joe Elliott <jee@xxxxxxxxxxxxxx>]

One of these days I'll post some pictures and tell you all about my 
wonderful spring break trip to Italy last week, but for now I have an 
actual car problem to discuss.

Long story short:  When my engine is running at 2000RPM with no 
accessories on, I see 14.5V at the battery; When cooling fans, 
aircon, and headlights are on, I see 12.5V.

Even at higher revs, there's a significant votlage drop when I turn 
on the headlights for example.  My first thought was that there must 
be a dirty connection somewhere--more current, bigger V drop across 
that connection.  But my highbeams are switched by relays that are 
right next to the junction block where the 8-gauge wire comes from 
the alternator.  They are powered from that junction, and grounded 
directly to the engine grounding strap.  So there's not much wire 
involved with my highbeams, and I can pretty much see all of it, yet 
turning the highbeams on produced similar results--what's going on 
here?  Is my alternator shot?

Thanks,
Joe Elliott
