When I first put the Delco 110 amp alternator in Winged1, I wasn't 
sure about which wire went where for the two small wires that plug 
into the back of the alternator, so I took a shot at it and 
guessed.  One wire is the field excitation wire, and the other goes 
to the idiot light.  When I started the car, all seemed okay, until 
I went to shut it off.  It wouldn't shut off, regardless of what I 
tried.  I finally put it in gear with the brakes on, and slowly let 
out the clutch to kill the engine.  What I am alluding to is that 
you may have a short or electrical weakness in the alternator that 
is associated with heat, and is providing a feedback current into 
the coil and other parts of the electrical system.  However, since I 
am no expert in automotive electrical theory, I will bow the 
collected wisdom in this group.  Let us know what you find.

PS - I wonder if a failing auxiliary relay could result in this 
bevavior? (relay 35 and 36 in the relay diagram)

near-perfect condition.  Recently, I took the car on a 130 mile 
trip.  When I arrived at my destination and turned off the car, 
everything shut down electrically except the engine!  I even pulled 
out the keys, and the engine was still running.  Thinking quickly, I 
opened the fuse box and pulled out the fuel pump fuse, which of 
course shut down the engine.  When I put the fuse back in, the fuel 
pump turned on again.  So I guess turning off the keys turned off 
everything but the fuel pump.  To fix the problem, I disconnected a 
battery cable, waited 5 minutes, and reconnected it.  This fixed 
everything.  Of course, when I drove the 130 back home, the problem 
happened again. It seems to only happen when I drive a considerable 
distance, as running to the store does not cause this problem.
