I am calling out all the alternator model a10 owners. I have put up a few posts but so far no one has got back to me. Prove me wrong that I am not the only
alt model owner out there, what a thought, I would like to know how others got round some of the problems I have come up against.

Hi Nomad.
I have one, engine No. DA10A 470 with its original GA7 frame. unfortunately it does not have the alternator..., crank, or primary, they were not with it when it came to me.
It has been my daily rider for about 8years, just taken it off the road for a refresh over this winter. I have always presumed it was an ex police bike, the log book says first registered July '66 and it is on a D plate so I assumed it was registered again after leaving police service.
I do wish I had the original parts, since owning it I have got hold of an outer alternator primary and I think I could extend the standard crank, it is the inner primary which is the problem, being bigger at the front end. It does have a slightly unusual battery tray.
Alternator A10 cranks were robbed to make hopped up A65's back in the day.
So really you are still alone.

Hi Chris
Thanks for the reply. I inherited the bike after a cousin passed away. Luckily it was still in one piece but attached to a Watsonian side car which was immediately discarded. You were saying that you were thinking about extending the crank to allow for an alternator. Don't think that would work as it is a different crank fitted to these bikes.

Hi
Did you use ‘alternator’ as a search value on this site? There are bags of posts on there down the ages including my own previous ones. What do you want to know specifically?
I’ve got an alternator A10 built from bits and it wasn't easy to get them, obtain information etc as the alternator A10 and A7s were built in penny numbers almost exclusively for police forces at home and abroad who needed more electrical power for the primitive two way radios in the 50s and early 60s.
