[Tigers] Electrical short during start attempt

After gassing up this morning I went to restart the car. When I turned the
key, I got VERY slow and reluctant turnover (not enough to catch) and heavy
draw on the voltmeter. Turned the key again for another attempt I got the
same thing and noticed a wisp of smoke from under the hood. When I popped
the hood, I noticed a burned/melted section of the wire harness in the
vicinity of the alternator. Dang. Once home (tow truck), it appears a
couple of ground wires had borne the burden of a short. One of the scorched
ground wires runs down the loom along with the temp sending unit wire and
(on my car) attaches to a mount for the coil on the intake manifold. The
other fried ground wire attaches to the base of the ballast resistor. I
have a one-wire GM alternator, not the stock generator.
I have the a wiring schematic, but a diagram of the harness and what these
two wires (or perhaps one wire with two connections?) are supposed to serve
as the ground for would be helpful. I could splice in some new black wires,
but that seems pointless without understanding what caused the short in the
first place. Any ideas where/how to look?
Thanks much,
