Hi,
Is there someone that can help me with a diagram, drawing or picture of the wiring of the Lucas 6v/60watt E3LM-MO dynamo.

If it maters at all witch coil side has to be connected to F and to earth. And witch brush needs to be connected to earth and to C.

If my memory serves me:
The two field wires crossed as they emerged from the field. One has a yellow band around it (it will be placed through the right hand hole in the end plate - the other doesn't and is fed through the left hand hole in the end plate - as viewed fron the brusg end with the armature at the top.

Looking down at the generator from the brush end, Armature toward the top, the filed wire with the yellow band emerges through the hole in the end housing on the right side and looped over to ground. It was joined at the same ground point by the left brush wire. The right brush wire went to the connector marked "D" and the field wire emerging from the left hole in the end housing went to the "F" connector.

Now this is the wiring for a positive ground Triumph E3L, but I think it is the same for the BSA.

John, all you said is correct. Would only like to add, I find it easier to remember that field wiring is dependent on the desired direction of rotation. So it would depend on the model of bike as to which direction the dynamo is turned in service. Using this you can fit any dynamo to any bike (if they mechanically fit) and wire to suit.

Then you can bench test by connecting D & F to neg 6V, and the body to pos 6V and see if the rotation is correct.

That's much easier on the old grey cells, don't you think?

Matters not which field wire goes to D or F as long as you "flash"
(polarize) the field after connecting them. THEN you need to mark one of them for the next time you disconnect (or reflash if you didn't).
As for "C ", I guess you meant D.
