has anyone ever experienced having an EBM die after putting a freshly charged battery into the grip? My EBM was working just fine. In fact, just re-worked. I ran through one battery, then charged it on a new charger. Put the battery back in the camera the next day, and the camera wont run! The crystal sync unit's light IS coming on when attached to the bottom of the grip, so it seems that there IS power, but the damn camera just won't budge!
