Hello, I've got a G-300 that had dead batteries. I got a couple of replacement batteries, and had little trouble installing them. When I replaced the batteries I noted the sticker that reads "After battery replacement contact AC with terminal (-) using tweezers." On this mechanism, the negative terminal of the batteries is inaccessible. I've looked all over the web, and found many tutorials on other G Shock models, but not this one. I can't find where to access that negative terminal. There is a "(-)" mark on the AC plate at the one o'clock position when looking at the back of the mechanism, and using a paperclip I shorted it to the AC plate for ten seconds, but the watch is still dead. I did measure the voltage of the new batteries and they are good. Is there another position I should try to access that negative terminal from? Is there something else I should try? If it's got to go to Casio, what general range of cost am I looking at?
