Minolta Hi-Matic 9 Adjustment Help

I have searched high and low to determine the electric adjustment procedure (exposure) for a this camera. Specifically, I am looking for which potentiometer does what with respect to adjusting the exposure. I even purchased a "repair manual" off of that popular auction site - what a rip off. It contains little adjustment info and absolutely nothing concerning the electrical components or adjustment.

Any help would be greatly appreciated.

Holy grail I would venture to say.

Researching google links for a service manual I ran across a site that said that model suffers from poor soldering. Crystallized solder connections are bad solder joints. A crack around a lead is another. You may need a service manual for Minolta meters which may not have been made public.
