• Hi there Guest - Welcome to the New BCF!! This has been a long process and I'm sure there will be some kinks to work out, but as of today, Feb 22nd, the British Car Forum has been migrated to this new forum platform! There is much that is similar to the old BCF but also much that is different. Please give it a chance as with all things new and shiny it will take a little getting used to. However, I'm coinfident that, once you get used to it, you will find it a much more user friendly platform than the previous, outdated software.

Wanted Wanted - C39 Dynamo [22258D]


Freshman Member
Hi All,

Happy New Year to a great group.

Looking for a date correct dynamo for my '57 TR3. It needs to be a C39 (22258D) with a date code in Jan 57 or earlier (say mid '56). The one I have now is a C40 with a '62 date so I eventually want to replace it with the correct one. It doesn't need to work but looking for something inexpensive that I can rebuild.
Please let me know if you know of one (and cost).

Hi George. I have a C39 that has been off my car for about 3 years now. I went to the dark side on originality and installed a Triumph Rescue bolt on alternator. My car is a 59 TR3A TS42756L, but this C39 is not original to my car. It is 22258B and looks like a date code of 1 53 which makes it quite old. It was rebuilt for me by a British Vehicle Electric shop near Toronto. The other minor consideration is that it is negative ground polarity. Would this unit interest you? I have tried to attach a few pics. I live near Toronto, Ontario, Canada.
