if you want to fit an Alternator it's best to fit a Lucas ACR17 like was fitted to later +2 Elans.
At least that would be inline with an option when the cars were built.
I am still running as original on my Sprint and can't convince myself to fit a Lucas ACR17 for the moment.
I have only just fitted a Cigar Lighter because of Car Club Rallies and GPS.

Alan,
I have wrestled with this question. None of our cars are 100% original, the old 'ship of Theseus' question comes up. If you are prepared to use modern replacement parts, then even if they are patterned on the original, the car is no longer as it was in period. The question is where do you draw the line. Is it cosmetic, or functional or striving for full 100% originality.
The old 17ACRs weren't great. Heavy, relatively low output and unreliable. On the Elan, the regulator at the rear gets cooked by the exhaust. The Denso alternators are better in every respect. If it is not going to be original, why pretend? I have a similar view of the Jenvey historic DCOE throttle bodies. Well engineered, but what's the point?
My current view is that changing certain components (alternator, decent sized rad and fans, geared starter, electronic ignition, rear drive shafts) enhance the experience of owning the car and do not detract. I have kept all of the original parts, and if someone in its later life wants to refit them, then that's fine.
Others may have a different view.
Andy.
