If you don't care how it's done so long as it doesn't use a transistor then you may have more luck. However, a transistor is by far and away the easiest solution; a MOSFET doubly so. | |

| Feb 13, 2016 at 9:09 | comment | added | lobirkeland | The voltage of the battery is 3.0V. "black cable" should be "black arrow". I have a digital voltmeter and when a push the button with the yellow arrow it is connection between the the cables that i have pointed out with arrows. | |

Added voltage of battery, corrected the part with color on cable/arrow

| Feb 13, 2016 at 1:46 | comment | added | James Waldby - jwpat7 | This might be answerable by someone who has the same model of clock to test, but its otherwise unlikely unless you add a bunch of information. Eg: What brand and model is it? Is it battery operated? What's the battery voltage if so? Do you have a digital voltmeter to take measurements? Do you have an oscilloscope to look at waveforms? By "black cable is the clock gnd", do you mean the red wire with a black arrow pointing to it, or do you mean that bit that appears to be a black wire next to a gray wire, near test point P14 at lower left? | |
