Just to shed a little more light on the aperture position sensor, it's not a continuously variable resistor in the normal sense of the word. It is in fact a resistor ladder with taps along the series string terminating in gold printed contacts, it appears to provide 1/6 stop increments (MX aperture position sensor).
