OK, now if Jack had just taken the pictures I asked to start with, we could have skipped the last 2 posts. As it turns out all the wires (that I have seen so far) do have the specs on the sheathing as specified in the PO.
So all is goodish, though the lack of communication and clear lack of comprehension on the significance or the wiring has left me a tad uneasy but on a technical level, things are back on track it seems.
So next up is to confirm shielding on wires going to the motor controls and spindle. And get a picture of the correct relay for the vacuum.
Have I mentioned this is tedious yet? Pics on next post.
