Wiring diagram to -60 BSA A10 Police Model

[BMH]

Does anyone of you know where I can get a wiring diagram to a -60 BSA A10 Police Model?








Regards from Norway!

BSA Service Sheet No. 813A covers this matter. Six pages, including diagrams.
If you can't get this locally, email me and I'll scan them to you.

this thread's got itself a bit split between frame data and wiring diagrams .  . I for one know nothing about side-by-side dynamos and alternators (presumably wholly independent circuits and batteries?), and would find more info on police models fascinating.
If one had an alternator primary chaincase, plus a late clutch with cush-drive, how easy would it be to stick an alternator on any A7/10 alongside or instead of the dynamo? How different is the crankshaft in the driveside mainshaft department? Has anyone done it (short of buying Mr Plod's version)?
I muse, because I like alternators a lot . . . Although I freely acknowledge that dynamos work very well, considering their limitations . . .

Groily, the alternator and generator were connected together and controlled by the headlight switch. I have a circuit diagram in my service sheets.
The crankshaft is different. There was also an A7 version made, I saw one before it was stripped and it's components donated to more worthy projects. [who wanted an A7 in those days?]
There were two versions of the outer chain case. One was a solid casting and the other had a chromed plate over the alternator as per early Triumph.

Here's the alternator/generator wiring diagram.

Thanks a lot Trevinoz - just printed it off for reference.
Thought the cranks would have to be different, shame, otherwise it would be a nice conversion especially if one used a later 2 wire alternator which can be better regulated. I always envied guys with Tri 110s etc with mag and alternator when I was young. As you say though, who wanted a lot of these bits in those days!
Many thanks

Groily, you would have been disappointed with the alternator as there is only enough space for , I think, the RM15 alternator.
Can still be connected for 12V though.
Attached is the Police model supplement. It might take a few posts because of size.

Second lot.

Third lot.

Thanks again Trevinoz - all v interesting. RM15 better than nothing - but I'll stick with what I have on the A. Have just loved playing with an alternator B lately, which has given me all sorts of daft ideas! That has a decent (later) 2 wire jobbie, a new modern combined reg/rect and supports ignition and excellent lights . . . Enough idle thinking - back to fixing other things . . .

Nice work, Trev. In addition to these sheets, I sent BMH the wiring diagrams so he should pretty much all set.
Let us know how it works for you, BMH.
