Chuck, I jumpered what I believe to be the plug for the idle switch.  It is
a two wire connection, one of which should deliver (only) 5 volts or so from
the ECU and the other of which goes to a ground on the left head.  Unless
there's a resistor in series with the switch behind the socket, there's no
reason I can see why it should have fried the wires.  David Beirel
speculated that the circuit may have picked up 12 volts from a short or bad
wire someplace.  I'll investigate before I put the juice back to it.

Just to clarify, the "socket" is the connector for a two wire circuit from
the throttle switch and is permanently mounted to the top of the right side
of the engine.  The "plug" (where I applied the short) was removed from the
socket at the time.
