12 Volt Conversion
Yes, that is the Triumph type and I think was designed to fit at the front of the bike just behind the forks, from your earlier description I thought you might have had the correct one.

You mean the one specifically for the Lambretta? I hadn't realised they had done one until now. I've certainly not seen such a beast. They must be rarer than a rare thing.
They cant be that rare, as I think I have done over 100 of this type of 12 volt dc Conversion... Probably better with a newer style rectfier... but for the original look of a 60's style conversion the Lucas parts are usually prefered...Doom Patrol wrote:You mean the one specifically for the Lambretta?

Yes I'm sure they were made especially for the lambretta and are indeed rare, unless they are all languishing in sheds and owners don't know what they are.Doom Patrol wrote:You mean the one specifically for the Lambretta?

Thats the same as the one I saw on a scooter in a 60's magazine and on the TV... late 76 ish... the one in the magazine was on a dealer special if I remember rightly.... Very retro...Doom Patrol wrote:Here you go.
Thanks for the tip about the book Chris.
The article I have is by Dick Sedgley and has a photograph of the lambretta concessionaires conversion kit which cost £12-£13 in '69, it clearly shows the heatsink is not the same as a triumph. Obviously the ones you have seen are homebrew or other dealers attempt. I wouldn't want a triumph one hanging off of my mudgaurd as they look fairly heavy.

Sorry but I didn't try to claim that they were original fitment I know the origins and the dealer exchange scheme that existed for the stator when fitting an original conversion... I only meant to answer Doom Patrol's question...
"Now I've got one of these complete with diode and my question is where and how do you mount it? I have seen a picture somewhere, but that was a long time ago. So any help in this respect would be greatly appreciated."
So I really was only answering Doom Patrols question... I saw your post, and I couldn't add to it, as its correct in every detail as below.
"This conversion was done by dealers, but it was an official conversion and could be specified on ordering a new machine. Lambretta concessionaires modified the stators and sourced the parts direct from Lucas, the heat-sink, I think, was specially made for the Lambretta.
The early Indian GP200s imported over here also used the same system, with the Lucas components fitted by the dealers. The zener was fitted into the air scoop under the seat, which is why Indian scoops still have a hole in the top. There it was cooled by sufficient flow of air and didn't need a finned heatsink, but it wouldn't be a good place to get a spark if you had a poor connection.
A more efficient system is now available in the form of a podtronics unit which will regulate and rectify, this has been purposely designed to replace the lucas components. The details are in the pathfinder thread on this site.
Any chance of a picture of your heatsink?"
The scooter I saw was a dealer special in either Motorcycle Mechanic or the earlier magazine, Motorcycle Scooter and Threewheeler, as you say probably a home brew... It might have been an S type but It used a Triumph type heat sink... as you say I wouldn't want it hanging off my scooter either...
But Lambretta did get the electrical system design from the British motorcycle industry (which is what I tried to infer) as this is how the Triumphs and others in the 60's were wired, which Lambretta Concessionaires copied... But got there parts direct from Lucas to use with dealer exchange stators or if ordering a new scooter the conversion carried out for you... The original six pole conversions being done to works Lambrettas entered in competitions in the 60's...
I spoke on the phone to Dick Sedgley when I first started running an Electronic stator on my scooter, and he knew what was wrong with mine just with a phone call... He was recommended to me by AF's when they were back in Watford... Dick Sedgley was recognised as an authority on Lambretta electrics by all that new him back then... I never met him, but I phoned him a couple of times around 77-78...

for those that don't know, Dick Sedgeley is the guy on the cover of the original Lambretta Workshop Manual, working on the TV200.
He's still about apparently, and is one of the unsung hero's of the Lambretta scene of the 1960's.
Long may he continue

And a Gentleman as well.... who was very very polite & patient with me no matter how stupid the questions were that I asked him... He got me to take an interest in Scooter electrics as I knew from talking to him that I could learn a lot more, as I realised that I knew nothing.... So if you are out there reading this .... Thank you...
