In the 1956/7 era, Lucas supplied BSA with a three prong plug and socket in the wiring loom that allowed the light to be removed for racing. I was told that RE used the same plug on some of their bikes. Does anyone have a parts list from that era that would show the electrical parts, and is it possible that such parts might be available from India? Before the latest computer meltdown, I had a site bookmarked which had the Lucasparts list that showed the plug and socket, with part numbers. If anyone knows such a site, I could provide the Lucas numbers. Thanks for any help.
Gregg, I sent an email to Waldrige, so we'll see if they have them.
Skip, that was the site I lost, so I book marked it for future reference. The part numbers are 863193 three prong plug, and I assume that the 838431 is the socket. I cant see the open end, but it looks like three wire coming out of it, so you were right on the money. Thanks to both of you for the help. I have a matching numbers bike, and it came with those parts, so I would like to put some new ones in. The ones there are really weather worn and cracked. Thanks again, Jerry
The original rubber part 838431 fits in a hole in the back plate, and has a cover that is hung with a chain, to be use when the front loom is removed. I don't see an elegant way to install the metal body of 860159 into the socket, nor do I know if the OEM plug pins would align with the plug. So let me see if Skip can come up with anything. Your efforts are appreciated, Jerry
Sadly, my sources are all out of stock, other than Mike @ Wallridge on the reproduction ones.The repros I have ever seen, were the Tri-Cor reproduction ones. I would either search the eBay listings in the UK & USA, or see Mike @ Walridge You may also want to check the owners clubs of other brands that used that part number, by reviewing the Lucasparts list, as an example, Ariel used that part number in the early 1950's, perhaps a post on the Ariel Owners site might help?

Two sizes were used on Enfields, I presume BSA would be the same (3-prong and 5-prong). I do not believe these have ever been reproduced except by a gentleman in England who repro'd the 5-prongs for Ford GTs (these style plug/sockets were used mainly in automotive applications for race and rally cars). I inquired about them a few years ago and he quoted me about $750US a set to reproduce them as he was out and didn't wish to make another run unless I could guarantee at least 5 sets! I backed down. I did find out that Massey-Ferguson tractors used them as well, though, theirs were 2-prong. I have hoarded a batch of these repros, though the caps are held on by rubber straps, not chains - this is easily fixed with a trip to a competent hardware store. Silver Fox Tractor Spares in the UK has these. Maybe not suitable for a concours d'elegance, but very few people would be able to tell the difference. A clever chap could prob'ly convert a two-prong into a three-prong as well... Hope this helps!!! -J

Thanks, but the plug carries battery to amp gauge, tail light, and system voltage to regulator, so two won't do. And if I were a bit younger, I would make up a mold and cast them in urethane for three prong. (To many projects in the waiting pile, and not enough years left to get them all done), I can imagine the time you spent finding the ones you did. Like hens teeth, they are. If nothing can be found, I may get back to you later. Thanks again, Jerry
