All the Lucas ACR alternators look and fit pretty much the same but can vary 
enormously in output (I use an MGB spec on my Sprite with 160W main beam).
Many years ago a friend had a mini van and when the alternator packed up he 
pulled one of an Austin Allegro and fitted it instead.  After a while there 
was a stench in the van and when starting the engine it made an amusing sound 
not unlike a piston engined aircraft (the engine ran a lot slower at idle 
than the cranking speed) - first time every time too.  Turned out the Allegro 
alternator seriously overcharged the mini battery and must have been in part 
due to some sort of fault with the alternator as well as its output.
