I have acquired this clock via an auction, with no instruction manual. There is nothing to indicate the age of the clock and it does not bear a makers mark on the dial. It appears to be a master clock for a slave clock factory system. At the moment it does not run. It has a fluorescent tube around the dial and is approx 15 -16" in diameter. I have been able to light the fluorescent tube using main voltage (as I am in the UK our system runs using 240v supply), but I have been loath to introduce this voltage to the clock mechanism as I am concerned about burning out any of the components. However, on introducing a 12v supply to the clock contact, one pulse occurs causing the yellow contact shown in picture 4 to close, but nothing else. This is my first repair on an Electronic clock like this, and I wonder if anyone can advise me what to do next,or whether it is worth trying the higher voltage.
