Mase generator circuit board. Generator doesn't want to start. Old school electronics without microcontroller, which logics consists of CMOS logic gates. Board was brought to me as faulty.
After drawing some schematics and figuring out how this board works it was tested OK! It is of great imortance to figure out how electronic board works in details. Why? Because I provided electrician the details of pinouts, where they are going and what he needs to measure, and what values there should be so that generator should start. And it avoids high costs of buying the new board which wouldn't solve the problem (if it is even possible to get another one), because the problem is not on this board.
