Are you sure you're not trying to clear traffic ahead of you.
I haven't read all posts, but have you taken some voltage readings across the battery? Or try setting the meter to AC and turning the range down till you get a reading.
I've read a few of the alternator explanations and started to
.
A three phase alternator puts out three sine waves, each 120° apart, producing three positive half cycles and three negative half cycles.
The diode pack (rectifier) flips the three negative half cycles to the top. The end result are six positive half cycles which overlap. The ripple follows the resultant until a battery (a capacitor) smooths it out to near DC.
Have a look...
