[urq] sudden stumbling

[Harten Eric C Capt KHQ PAOC/CODP]

I noticed another interesting issue today on my way to work.  I have
always had a low voltage condition on my car, but no amount parts
replacements or load reduction mods have helped.  I installed a 2nd volt
meter to monitor the alt directly.  Normally, when its cold the alt
reads 13.5v and the dash voltage reads 12.  In the mid afternoon heat
today, My alt dropped to 12 and my dash to 11.  Now for the interesting
part.  As I sat at the light, my alt voltage would DROP a full volt as I
revved my engine.  Why would it do that?  It is a new and tested
alternator.  I wonder if I have corrosion somewhere that is causing this
low voltage.  The fuse box is brand new.  Any thoughts.  I don't blame
the ignition system for not working very well at 11V!
