I have an olympus D-340R and would like to build a external battery pack. I have tried several plugs 1.7mm and others but none seems to make contact with the cameras recepticle. Is there a special plug or something I am not aware of? I am using 4 alkaline batteries and the voltage and polarity is correct.
