    Re: Does this Bridge Rectifier bottom look bad?

    found the problem.

    There was a short in the wiring to the second motor external wiring.

    I replaced the wiring harness and the system works great again.

    Thanks for all the help and understanding about the board.

    I would like a circuit ID if anyone knows where I can find it for the miracle one board.

    Thanks

      Bridge rectifier identification part number KPB305G
      by Steph.hen
      Hi all, a newby question about a bridge rectifier I'm trying to identify.

      I'm in the midst of reparing a battery charger in work which went pop, The bridge rectifier has shorted and took out a couple of other components. The rectifier in question has a part number KPB305G, and it looks like it's obsolete. Does any one know what I could replace it with?...

      Fujitsu Q556, What capacitor for bridge rectifier?
      by mpn78
      Hello

      My Fujitsu Esprimo Q556 motherboards blew up. At least fuse, bridge rectifier and capacitor got damaged. I have changed fuse and bridge rectifier (DF1508S), but I don't know what capacitor it is (picture). I know that capacitors size is 47nF, but I don't know other specs for it. Can you help me to choose right capacitor for my motherboard?
      There is 240V AC on input side of bridge rectifier and 340V DC as output on capasitors side.

      Thanks....

      Reading input and output of bridge rectifier on the same scope?
      by EasyGoing1
      I have a 40 volt AC transformer that I put a bridge rectifier on, and I wanted to see the input signal and the output signal on the same screen on my scope, so I set one channel up with the test lead on one side of the input and the ground lead on the other side of the input, then I used another channel on the scope and clipped the test lead on the positive side of the output then the ground on the negative side of the output.

      When I connected the transformer to power, the wire that was connected between the ground lead on the second channel and the negative side of the bridge rectifier...

      Diagnosing South Bridge (FH82H370) on Asus H370-Pro Gaming Motherboard
      by Ross Kohler
      Hi,

      I'm learning about motherboard repair and I believe I've traced the issue down for the South Bridge on the particular motherboard I'm working on. My path of concluding that:
      - There's no sign of any attempt to power on when pushing the power button.
      - No PSON signal is reaching the 24-pin ATX connector.
      - The Super IO chip is receiving the PS_SWITCH signal from the power button and is relaying this signal back to the South Bridge.
      - The Super IO is not receiving the S_SLPS#_R signal back from the South Bridge
      - If I pull the Super IO S_SLPS#_R pin...

      XFX 850w blown bridge rectifier.
      by leotron
      Hi, a friend of mine gave me this broken power supply, aparently it's the rectifier bridge that was damaged months ago. He took it to a technician and they didn't have the repair tools necesary but they remove the original bridge rectifier since it was damaged(burned). I have some of this rectifiers laying around, but they are not the same. The original its a pair of GBJ1506

      And I have KBL06 , KBL406 , RVB406, D5SBA20, D3SBA60, GBU608. Most of them have similar values to the original, but I'm not planning to use the PSU at full load (ie: SLI, an I7 processor, etc).
