I suppose I should also comment (for those who don’t know) that the stock AC-Delco in a TC is English made. It is similar to an American made Delco of the day, but is not the same. Unlike the American Delcos, it has an awful reputation for reliability.
I see the Boschs on ebay all the time, advertised as Lucas replacements, for what I consider outrageous prices.
Attached is a screen shots from O’Rielly Autoparts, showing the Bosch alternator. It comes stock on an early 70s Capri. Or just go to
www.oreillyauto.com and type in part # 13138.
The Lester # is a unique number that identifies an alternator, give the Lester number to any rebuild shop and they can supply you with that alternator. The Lester number for my alternator is 13138.
It comes on a Capri with an external remote regulator, but any decent rebuild shop can fit a regulator (I believe it the black box bolted to the back of the Bosch in the photo). You will need a correctly sized pulley, but again, no problem for a decent shop.
The Triumph/MG people have been doing these conversions for a long time, there is plenty of info on the net. For wiring instructions see their sites, such as;
http://www.74tr6.com/alternator2010.htmhttp://www.triumphexp.com/phorum/read.php?2,913842http://www.tiggersavage.com/ford_alternator.htmBe warned that the flange clocking on a TR6 is different than a Europa. The clocking refers to the orientation of the alternator belt adjustment bracket flange to the primary alternator mounting flange. It is at 2:00 o’clock or 10:00 o’clock? Thus the specific Bosch used on a TR6 will not work on a Europa because the clocking is different. Ask me how I know?
I don’t want to beat the drum too loudly for the Bosch, as there are other options. My local alternator rebuilder offered me an American made Delco, and Bean used to sell a Japanese alternator, both bolt-on swaps for the English Delco/Lucas. I selected the Bosch because it was cheaper at the time.
