[QUOTE="timetraveller, post: 99974, member: 456"] Several years ago Dick Sherwin and I came up with a design to fit a small car alternator to a Vincent. We came up with designs for all post war models, singles and twins. On the singles the alternator takes the place of the rear cylinder and does not interfere with any other parts of the bike. On twins we had to design in a replacement for the dynamo which drives a poly vee belt which then drives the alternator. All the early ones were based upon an Iskra 30 amp alternator intended to be fitted to 2CV Citroens and similar. In order to keep the price down I was having to buy these in tens. About 80 were sold and many of the long distance riders over here have them. I have only made one in the last few years but suddenly have orders for four. Following a single installation of a 40 amp Nippon Denso alternator several years ago for Peter Holmes I decide to fit the Nippon Denso ones to the latest batch. These are 40 amp units with the regulator built in and it turns out are very popular with the kit car people. I have had to re-design several of the parts and am currently waiting for some bits to be made so, to those of you who are waiting, sorry but that its the reason. I can provide more details if anyone is interested but should warn people that I am having trouble sourcing the alternators. Several years ago I was able to buy them for about £50 each. Now the only way to get them quickly is to pay about £120 and so I am buying them in ones and twos when they come up on the internet. I could send photos or other details if there is any interest but they are not 'off the shelf'. [/QUOTE]
