This is what I have found:
1) The internal ide port seems dead.
-- When a drive is 100 percent correctly attatched I get one of two results: It either isn´t seen by scsi.device, or my machine has a black screen for ever while fans and leds work
2) The PSU might be dead
-- It has now killed two CF adapters, two IDE harddrives, one SCSI disk and two CF cards. Burnt them out.
-- It is one molex in particular that kills disk, when disks are connected to this molex. They start to sparkle, smoke and burn
3) The 68060 fan might be dead
-- The molex that kills has a splitter on it that powers the fan glued to the heatsink on the 68060 on my Cyberstorm PPC
Good news:
Ive tested the PPC, the CybvPPC and PIV - all working.
So My questions:
1) Where do I get a new fan for my 68060. It seems like it´s screwed in. Do I just google for a same size fan (mm)?
2) Where do I get a suitable new PSU. I´m in Europe and my machine also needs power to the Mediator. Currently, the Amiga PSU plug is soldered on my current PSU.
3) Is my IDE dead for sure?
-- Can it be salvaged? Repaired? Maybe it´s just a new IC or Cap that is needed?
This is a very very depressing day :bigcry:

I feel your pain. Where as my A4000 problems aren't as bad as yours, I too have a non fully functional motherboard. For the IDE issue, you can always get an IDE Zorro II or III card and use that, they might be slightly faster, and for the power supply there is a gentleman here who makes ATX converters so as to allow a newer power supply to be used. I don't remember his screen name unfortunately, but he usually ends his posts with his real name with is Nathan, just like me. The Fan should be the easiest I would think. Identify the fan size (usually in mm)then see if you can find a replacement with the correct power connector. Sorry if I'm not much of a help, but I wish you the best of luck with getting your A4000 back up and running.
*edit* - Sorry didn't read as closely as I should have for the IDE whether or not it can be repaired I am not certain. I thought one of the Chips on the board ran that, but again, I am not certain on that. Others will know more than me.

@new2amiga
Thanks, I hopy you also resolves the problems with your machine.
@thread
I just contacted AmigaKit and asked them what the difference is between the two adapters ADAPSU004 and ADAPSU009
It seems that ADAPSU009 is the more complete product, and better suited for my Amiga 4000D in PowerTower with Mediator4000D

Hi Arnljot,
These are complete & stick on solutions for the CPU.

I have an A4KD PSU which I ripped the guts out of. I have shoe horned an ATX 400W PSU in it & hard-wired the A4KD Mobo Feed into the ATX pcb. It's not yet quite finished & will need commisioning. It would be ideal for ample power to any heavily expanded Amiga. -but-
You mention Mediator so, guessing you have it in a Tower, that version of Mediator requires a P9 connector from an AT or ATX based PSU. If you are towered on Mediator, I recommend to a specific Convertor like this & you need to acquire a working ATX PSU obviously!:

RE the IDE, it could just be the knackered PSU casing the problems. Can you put an IDE CDROM on the header? - They draw a lot lot less power than a hard drive. - Could also be blown or leaky Caps on the Mobo. Have you looked for wet/sweaty tops? - Is the IDE cable sound?
Good luck there m8. :-)
