FHP Motherboard Asy S1609 Help

[MayContainNuts]

Hi all,

I have nearly rebuilt my Denford Orac.
Still running all the old electrics but they work fine.

But I have one problem!
When I bought this machine it had four wires removed from the connections.

Looking at the back right hand side of the machine is the following;
A black cover held on with 4 screws with an electrical power sticker on it.
Remove this and you will see a boad with the following;
8417 FHP Motherboard Assy 100659D
The conections that are removed are;
Output Voltage Gnd 1 2 3

I have a 10mm thick grey cable with four wires comming out of it;
Green/Yellow
Blue
Black
Brown

These come from the connections Gnd,1,2,3

Any one know what goes where?

I think the board is a S1609 but not sure.
Please find a picture below of the board. The connections I am looking at are in the bottom right corner (output Voltage)


Any help would be good.

The manual for that is here:

It's 3 phase output so just connect the green/yellow to GND terminal and the others to 1 2 and 3 - am sure order won't matter but you may need to swap two phases if it runs the wrong way.

Hi!

I understand this was an old post but in case you are still here can you please tell me where those heavy gauge gray wires go. Mine were both broken and I have no idea where they were connected to...One is the gray wire coming from the large blue filtering capacitor (secured with the yellow screw) and the second gray connects through the red coaxial connector to a short black wire. It must be that... one of those was connected at the other end to a low frequency choke which is now missing from my machine.

Any help with this problem would be highly appreciated.

Thank you in advance.
