The polarity for the clock must be changed to negative ground from positive ground. You may need to remove the clock to do this. There is a little tab that is designed to be positioned for positive or negative ground. Position it for negative ground. Major damage will occur if it is powered up in reverse polarity. Install a 125-ohm 10-watt resistor in series with the 6-volt clock to drop the voltage to 6 or 7 volts.
