... begin to suspect 2 capacitors 220uF which I think they are responsible for 12V power. It looks like cheap-shit and can see cross on the top of case what is never to see with quality one. i think I will order Japan capacitors 105C and replace it.

The "cross" is a protective measure. From the site: http://www.ami.ac.uk/courses/topics/0136_ec/

The main concern is internal heat and gas generation, and fault conditions may cause sufficient internal pressure to rupture the can. This is why large capacitor cases have an integral pressure relief: with small capacitors, this may take the form of a rubber plug at the lead exit or, more commonly, a deliberately weakened area (often seen as a pressed cross on the end of the package) which determines where the rupture takes place.

So if there is no rupture that is not an indication of "cheapness" and no reason to suspect the capacitors.

I'm well aware of this. But....if you check high quality Japan capacitors you never see this weakened area. Also I see many cheap capacitors which was not ruptured yet, they were only swealed and decleared 'good for garbage'

.
Anyway I was in contact with seller and they sent me picture which contact of relay I should shortened.
Problem solved, safety decreased but hashing...for now.
