To check the power supply of the clock, locate the electrical connector and find the pin on it which supplies the power (12v) to the clock. Take a small bulb and socket and bridge a wire from the 12v pin supplied from the electrical connector, to one of the two wires on the bulb and socket. Next find a ground supply nearby ( the best place would be the key hole) and bridge another wire from it to the second available wire on the bulb and socket.
