OK, a Junghans ATO came in today with a dead battery. I noticed that in Merritt's catalog, there is a conversion box to accept 2 AA batteries instead of the old box battery. So, since it is on backorder, I tried an experiment. I tape two AA's together, ran a metal contact to connect both positives and negatives together and then ran the two wires to the batteries. Nothing. I reversed the wires and still nothing. Am I being to literal by tying the batteries together as I have? Do I assume the red wire is the positive and the yellow negative? How can I test it for magnetic operation? Thanks, Chris.
