Title: Dynamo/Alternator
Post by: Dave Gee on 04 May, 2013, 08:57:58 AM
To get the best of both worlds, I have just had my dynamo made into an alternator for an early S1 Fulvia. Picture attached. There is a possibility of getting a batch made.

Dave, it looks excellent, any idea what it would cost if you have a batch made please ???

Would it not be easier to fit one off a 2CV?!   Seriously, as it is well hidden by the inlet manifold, why not just fit a more modern alternator - it is easy enough to change the pulley for a V type?

Hello David

I think the problem using a modern alternator might be finding one with the length of body to take the long single bolt mounting. This mounting is the particular feature of the S1 Fulvia block (long cast on sleeve through which the bolt slides), which is absent from the S2 block with its alternator (cast on lug on block for rear mounting and bolt on plate for front mounting).

Hello Dave

Can I repeat the request from Brian as to price costings.  Also, what other alterations are required to substitute the mechanical Bosch regulator of the S1 dynamo?

Regards - Roddy

There is a PDF wiring diagram at http://www.classiclancia.com/car-parts/index.php?route=product/product&product_id=93 also anyone know what this photo is?

These solutions with extended front pulleys must surely excessively load the tiny alternator front bearing with this bending moment, especially as you have to have the belt really tight.....

Tim, I'm inclined to agree with you and a good reason to stay with Dave's solution of modifying the dynamo with a front bearing which is designed to take the extra load.
I also like the idea of overcoming one potential problem without spoiling the appearance of the series 1 under the bonnet.
Must say though I've never had a problem sticking with the Dynamo on my 1969 1.3 Rallye Coupe, or "Fay" over the last 15 years as long as you didn't try to run everything at once, but with no heated rear window, or Radio there's not a lot else drawing power :)

Yes,
I am with you Brian. Fulvia dynamos have always seemed up to the job and reliable so why change?. Aurelia dynamo's are a bit more marginal (and of course are necessarily older). Various alternator conversions are available (I have tried a couple of them) but really the dynamo is fine if in good condition  as long as no addititional electrical equipment is fitted and all switched on at the same time.
The Aurelia alternator conversions all save weight as well.

I should have said I overhauled my Flavia dynamo as a precaution as it didnt seem to have been touched in the car's 65000 life.

I just needed one exoticly designed huge brush (the other one was less than half worn - but I bought two as you do). It seems to cope and like Brian I have no radio (yet) and no heated rear window....

I like to stay original too.
