Mk111

Kits Timers and Clocks

Hello,

I bought 2 mk111 kits and both don’t work.

When pulse is on, I have electric current between : 1 and 5, 4 and 5. But nothing between 2 and 3 (strange …), 2 and 4, 3 and 5.
Same thing with the 2 kits.

Could you please help me ?

Thank you beforehand.

Solders seems good.
Can you post a picture of the component side?

Thank you beforehand.

Please note that the output of this kit is a dry contact (a switch).
There is no voltage coming out of the relay outputs.

Ok I understand, so it is why I have no voltage (I do not know the working of a relay …).
I found a solution : I pulled out the relay and linked 2 to 5 and 3 to 4.

Thank you for answer !

Please note that if you do this, you will have to be careful that you do not draw more than 100mA of current, otherwise you will destroy the transistor.
