Hi all, I was hoping to get some help dealing with the consequences of a ‘schoolboy error’. I took out the faulty motherboard from my 6 yr old conquest mini lathe without photographing the lead connections… so now I have no idea how to connect the new one. Does anyone have a picture to guide me? Have contacted Chester who have tried to help but I can’t understand the manual and the pics they sent are of a different machine. Any help very gratefully received. Inigo

There are a number of wiring diagrams for various mini lathes/mills here : https://littlemachineshop.com/info/business_resources.php?ID=1876291636&CAT=1

Post up the board model number if it has one or a photograph of the board…..I'm sure we can help get you wired up again..

Have just checked the invoice and apparently it is a BC2000 board. Inigo

Ian, can you post a photo of the board please? I think it may be a KB clone board..,

To get you ' in the mood' you should have, as a minimum:

3 wires from the speed pot

Four wires from the Forward/Reverse switch.

Two wires from the mains filter, they may be Brown and Blue…

Post back when you have located them all…

If you post some pictures of the old board and the new board there will be more chance of someone being able to help,
Here is a link to the manual, The wiring diagram is near the end of the manual

Hello all, I have pictures on my computer but there does not seem an easy way to browse for these and attach them. How do people do this? Many thanks, Inigo

You need to go to albums, (On the top of the page on the same line that you use to log in.) Then create an album and then upload the oictures to you album. From the box where you type a reply you can then insert the pictures by clicking on the camera button at the top of the reply box.

I have found this link that seems to show the same board, There should be two wires from the reversing switch that connect to the motor via the reversing switch. Verify you have the correct ones with resistance measurments. These will connect to A+ and A- on the board. I You connect them the wrong way round the motor directions will be reversed. If this is the case just swap them over. The live from the mains fuse (Yellow ?) will connect to L1 The neutral from the on/off switch will connect to L2. The slider on the potentiometer connects to P2 The wire from the clockwise end of the potentiometer connect to P1 The wire from the anticlockwise end of the potentiometer connects to P3 I suspect that you will have one wire over. I suspect that this will go to the the connector near trimmer R3. I don't know what that connection is. ( On your picture it looks like a green wire goes to it.) You will have to trace where the extar wire goes to to work out what it does.

You should find that they use different sizes of connector and male and female in different senses to make mis-connection a bit harder.

My old mini lathe had any ambiguous connectors fitted with numbered tags (as does the SC4).
