Hello everybody, I'm a french newcomer here and have no serious knowledge about electronic circuits and components...
However, I'd like to know if I may modify the MK111 with a capacitor to let the 555 and it's relay working (for 1 second or 2) when I stop +12V DC on "screw 2" ?
If so, what would be the new capacitor value ?
Should I have to change "D3" ?
Here is a pic.

Thank you in advance.
Note : the checked consumption is about 50mA NC and 9mA NO, frequency about 1Hz
