G3 / Model 16 • Lucas E3AR dynamo internal wiring arrangement

I’m in the process of rebuilding my Lucas E3AR dynamo from my 1946 AJS Model 16 with new armature, bearings, brushes and field coil. My dynamo was a real mess internally when I disassembled it, and I didn’t think to document the internal wiring layout, and am now uncertain whether I have it correct for reassembly.

I have enclosed a mockup of how think it should be based on various bits of AJS and Lucas documentation, can anyone confirm whether or not this is correct or whether it needs amendment. Or have I got the connections to the left and right brushes the wrong way around, and need to swap the brush connections to the Earth and D terminals? Or does it not matter?

I’ve also enclosed the schematic for the E3L dynamo from some Lucas documentation.
