Everything is connected, facing a new wall, cant connect one of the unit's "+" to the second identical unit "-" side to form dual-polarity PSU(series connection).
Transformer has two secondary windings... interesting that i read 30V on multimeter if probe is connected to the first unit output ground and second unit positive output... seems that they share something...
Any tought's someone ?
EDIT, I found the problem and its good to know if u are about to build PSU.
If you buy an ammeter+voltmeter(dual-led light blue/red display) from e-bay and you plan to buy them 2 for split(series=dual-polarity, symmetrical configuration) then build also 2 identical power supply's to the ammeters/voltmeters from e-bay
. I had ONE
5V power supply for TWO ammeters/voltmeters
and i couldn't connect power supply boards in series(short-circuits, lots of firework from output pins) because of ammeters having 1 power supply
... So i build 2, each 5V, now totally separated.. everything is in place now and working good.
I will photo the work Tommorow for a preview to give u some motivation to build your own:D
