Hello,
I'm hoping someone can help...I'm putting together my first project, a Hairball 1176 Rev. D, and have a question regarding testing the power circuit.
I've stuffed all the components and wired the PCB to the IEC connector, checked and double-checked the grounding and transformer wiring, but when I test the power rails out of the secondary I get no DC readings at all. My question is:
Do I need to plug the unit into the mains? I'm in Australia (240V AC). I'm not in a rush to fry myself, but it seems hard to test the power rails without running power through the circuit.
I'm going to take the unit to an electronics repairman to check over everything before I plug into mains power. I just want to know whether the 0V DC readings I'm getting without the unit plugged in are correct, and not a sign that I have wired things incorrectly.
Thanks
Stephen
