Have a look a the site above. It relates to a Ford Consul, but it does use the Lucas 17ACR that was fitted to Minis on occasions.
Good Luck.

Changing the system is very simple. The hardest thing is to get the alternator bolted on with the right brackets, and lined up with the drive pulley(s)! Now If you want to use Lucas ("prince of darkenss") electrical system, you might have a couple things to do, such as is the voltage regulator separate form the alternator or not? The Lucas in my MGB is built in regulator, and very simple hookup!
Most later alternators have the regulator built in. All you have to do is have a heavier wire going from the alternator to the battery (output), - since the alternator will put out a whole lot more current, and could "fry" the one the generator used! You will need a wire providing power from the ignition system in "run" position, to the "f" terminal (field)-- - (although you could get by,- just wiring hot from output connection on alternator too, - most marine applications use this method with no ill effects). Put one on my brothers Fordson Dexta diesel tractor 15 years ago, (Was a delco from Chevrolet), no problems so far!! The second wire on the alternator "plug" is for the "idiot light", (and system will charge fine with this wire disconnected even). Hopefully this car has a ampmeter, - which should work ok (provided it is in the circuit to battery from alternator) -and it is high enough capacity to read what the alternator can put out! You can look at just about any typical alternator circuit and figure out pretty easily how it will have to be wired! Since the generator wiring is very similar, you should be able to figure it out!!
Have a look at http://www.vintagecarparts.co.uk. they do an alternator which looks and fits like a dynamo.
