Working on a new project, after installing BR's cap kits, replacing headers, installing a PS rebuild kit, including the 2 IC's and the 2N6059. I go to power it up after getting hold of a known-good power supply and F3 pops right away leaving the second LED for +12v not lit.
I realized I had a cap in backwards on the soundboard (the black one in the middle, top right) when I heard a hissing. I installed it the right way hoping no fuses would pop, but F3 did again. So that's when I disconnected the boards from power all together.
I've been reading through threads and think I may have narrowed it down, but need some more direction. I did Dokert's tutorial on reading bridges and BR2 likes to beep at me with my multimeter. So I figured I will replace that.
I did some measurements across the 2n6059 transistor's 1&3 pins, I get 9.86 if I did it right.
From fuses F5 and F4 I get 22.2v. TP4 I get 4.95, TP5 is 14.83 and the other TP5 is 15.20. I couldn't find a TP1 so I figured what I read might be for another power supply, maybe defender.
So now my head is spinning. Aside from replacing the recitifers, what else should I test? Or any other advice.
