The diagrams above in PART I, I believe are the clearest. However should you require additional information please refer to the diagrams below.
Wiring Key STURMEY ARCHER LIGHTING & DAU/FSU/DBU UNITS
So one may understand what part numbers go to what lengths & connectors of wire which existed. Earlier versions use eyelet tabs and terminal connectors. Later versions used "butt" style plugs into cylinder shaped terminals. Both terminals/connector types can still be obtained from hardware and electronic stores like RadioShack for home made replacement wiring schemes.
REPAIR OF DAU/FSU UNITS
Directions for repairing a DAU unit which may also apply for repairing a FSU unit. Over tightening of the central terminal or cap nut can twist the internal connections to the bottoms of the terminals resulting in a faulty connection to the rectifying circuitry. If this occurs it is only a matter of carefully disassembling the unit to the point that the tabs can be bent back into position (or re-soldered if necessary), reoriented properly and properly reseated in the battery tube. The photos below should be clear enough to allow one to figure this out.
Lamp information
See this post for HF-62 HF-625 HF-63 lamps manufactured ~1940-1960
http://www.bikeforums.net/showthread...natomical-Tour
"HF-62 is listed in catalogs as being "complete" with a 2 amp bulb "for Dyno-Luxe" and the HF-63 complete with a 3 amp bulb. The tail lamps (TL series with different numbers) had 3 different series with very different styles back then as well. The HF-62 is always shown wired to a GH6 dynohub with the Dyno-Luxe in the circuit. the HF-625 is always wired to AG-3 or AG-4 hubs (with or without a battery), and the HF-63 is always wired to GH6 hubs with or without a Dry Battery Unit but never a Dry Accumulator or Filter Switch Unit. Wiring was listed as GL or GZ base on whether it had the brass butt plugs or the earlier eyelet terminal connectors.
I assume the different early lamp models were the same save for the bulbs and the included flex wires. Later on there were all chrome versions of these style lamps before the two more bullet sized shapes with the different plug style innards were produced. I didn't even realize there were two sizes of the bullet shaped chrome lamps until I accidentally bought one off Ebay. According to 1950s literature, once the bullet shape had become standard, the larger ones were referred to as "Roadster" while the smaller ones were "Sports" models."
