Series II alternator or dynamo?

Title says it all really! Are Series II and Series IIA Land Rover electrics driven by an alternator or a dynamo? If both, as I suspect, did the change over take place on a specific year model, e.g. 1968?

my 66 2a ex army ffr had a dynamo, converted it to an alternator though

dont know the changeover but my old 67/68 IIA was originally a dynamo which had been converted previously.
It was petrol but doubt that makes a difference.

Hi all, my series 2a runs a Dynamo, pain in the arse and i want to do a conversion, can anyone tell me what i need to do it?:doh: its 1970 by the way....

I was just thinkng what the conversion would take and cost myself. Thanks for the replies by the way.

My 1971 Series 2A still has the dynamo (which just died). I'm planning on replacing it using a conversion kit and switching over to a ProLine alternator so I can run all my lights and other gadgets. @Batfink; if you live in the states try out a company called Rovers North at: roversnorth.com. They sell a bolt on conversion kit, just supply an alternator. I use them for all my parts and tech. advice needs and they haven't failed me yet .
