I'm still hoping someone out there can help me understand how I smoked the
wires on my throttle valve idle switch circuit by shorting together the pins
on that plug.

The plug I'm referring to is the one that plugs into the throttle valve
switch connector which is mounted on top of the right side of the engine,
fastened to the bracket that holds the metal coolant pipe which runs
transversly across the top of the engine.

According to my understanding, the throttle valve idle switch does nothing
more than close a set of contacts when the throttle is at idle.  This would,
in effect, put a short across those wires, just as I did when I jumpered the
plug.

TIA.
