I think you would want to keep current from flowing from the alternator back
to the ignition switch. If this is the case then you would want the banded
end (cathode) of the diode going towards the alternator. I would guess a
1N5401 or -02 would be a good choice for this. It is rated for 100 V or 200V
PIV (Peak Inverse Voltage) which is way overkill. Either is capable of
handling up to 3 amps forward current. They should be readily available at
Radio Shack.
