I'd get out the DVM and attache that to the red-white wire and ground and
the set to wriggling things.

Keith,
It sounds like you have an intermittent short to ground in the white/red
wire
from the ignition switch to the starter solenoid, or perhaps a short in the
switch itself. The fact that you are getting a full "D" reading on the
ammeter when this happens is the clue. The only way the ammeter can read an
excessive discharge with the headlights off would be for the excessive
current to run through the ignition switch. Since you only get the "D"
reading when you are trying to start, that leads me to believe it's the w/r
wire. The short in the wiring drops the voltage to the solenoid enough that
the solenoid won't fully engage - thus the click.
As temporary fix/test, disconnect the white red wire from both the ignition
switch and the solenoid and replace it with a temporary jumper. If this
cures
the problem, then you need to make a permanent replacement for the w/r wire.
If not, hold the key in the start position for a moment and feel to see if
the switch gets hot. If it does, the short is in the switch itself.
I may be missing something, but I believe this is your problem.
To get a better understanding of my statement about the ammeter reading
being
a clue, see: http://members.aol.com/danmas2/ammeters.htm
