Peter -
        The ingnition relay prevents current overload thru the ignition
switch.  When the switch is on, the relay provides power to turn
signals, instruments, brake lights!!, radio (I think?), maybe a few
other things.  It does _not_ power the ignition circuit.  The car will
start and run without the relay - still will have power to the fuel
pump.  The fuel pump is powered via the inertia switch.  This is a handy
thing if you are working on the car and don't want the fuel pump running
- reach under the dash and pull one of the wires from the inertia
switch.  Makes a handy anti-theft device as well.

Happy Holidays to all!
