Kieth,
I would guess that you have an intermittant bad connection somewhere. As you
bounce over bumps in the road, the connection becomes loose, then tight, etc.
When the connection is loose, it is a hogh resistance, and drops more
voltage. When it is tight, the resistance is low, and less voltage is
dropped, leaving more for your lights. Since it affects both your voltmeter
and your headlights, I believe your bad connection is at the "terminal box"
on the main battery cable. These are exactly the same symptoms that Kerry
Forres was having before his wiring meltdown. I believe it to be here,
because this is the first place where your headlight wiring and your
voltmeter wiring have a commonality, other than the battery cable and the
alternator.
I would start here, and check those connections closely. This connection
carries ALL of the current in your car, so you do not want a hot spot here.
Pay particular attention to how the terminals attach to the main cable. You
may need to replace the cable. This connection to the main cable was the
cause of Kerry's fire. If this doesn't fix it, you may have a bad regulator
in your alternator.
