Electrocraft Ultra100/ help needed

[fuzz_one]

Would anyone have or be able to point me in the right direction to find a circuit diagram of an ultra100 or similar drive.
I brought a drive on ebay (in as is condition) that has a problem.
Problem being in the power switching pcb board not the brains pcb board.
Looks to me that it may be going into over voltage condition and keeps cutting in and out eg fault led flashes and fan starts stops both in sequence.
Any help would be appreciated.

Thanks Dave

I can't help with the circuit diagram. Do you have the software for these drives? Does it tell you anything about the nature of the fault?

[fuzz_one]

Yes I have the software and all associated manuals in pdf form, but it doesn’t go into the nitty gritty of how these units work. Circuit diagram would make life a lot easier.

[unterhaus]

did you hook up the software to the drive and see if it tells you anything?

[fuzz_one]

No, I assumed because it did not power up it would not let me download drive parameters.
Will try, and see what happens, although I don’t like my chances.
