I thought I had this licked when I ordered one of those battery adapters (two actually, one for each of two Super Pilots) from Thailand. I tried them in both Super Pilots with an LR44 battery. Meters act like there's no battery installed. I know they work because I tried them in the light meter on my Nikon F and they work fine. The meters are working with 1.5 V batteries installed. I guess my next option is to place a 1N5711 diode in series with the battery. Any guidance to how to do that would be greatly appreciated.
