David's Mini Lathe......
Stilldrillin:
Hi John.
This evening, I have checked the wiring against the little mc shop diagram.
All is correct. Though, several terminal screws were a little loose.
Tomorrow, I'll apply the meter...... :zap:
Joules:
No worries David, the schematic is here for you and others. Perhaps over time we can build up a table of test points and voltages for others to fault find from, as it seems a common problem sorting these boards out.

We are looking for a low value that is causing the 3A fuse to blow......

Is this low enough, John? :palm:
John Rudd:
David, that is a low reading, likely to cause a fuse to blow....
I see there's a little power supply in one of the previous fotos, can you disconnect the power feed to it and measure again?
If the reading is still low, can you disconnect the mains wires going to the speed board and try again...?
Stilldrillin:
John.
The speed control knob doesn't click, off. In the stop position.
Thinking this might be at fault, I disconnected all three wires. No difference.
The feed wire to the transformer, is already, not connected to anything. In the pic, it lays over the top of the control box.
I have also pulled out the plug, where the wire to readout connects.
No difference...... :bang:
