Hi Forummmers! I bought a used nikon MD-12 few months back and it has been working awesomely! Recently, the winder was not working as fast as it should be, the 'sound' it gave was kinda diying, so i changed a new set of batteries (all 8 of them) and when i turned it on, tested it, it did not work! I tried the 'coin' testing on the tip of the connector (4 pins) and all i can see is a half lighting on the LED, which sometimes on and most of the time dont, It does not wind anymore, any suggestions what might be wrong with it? or is it a sign of true deadness and i cant do anything to revive it? Regards, Aezran.
