Royal Enfield Bullet alternators look very like the unencapsulated Lucas ones on Nortons. Would one fit? They are cheap and certainly effective - the one on my 1998 Bullet works a treat.
With all the tales of woe with fitting a new Lucas alternator this could possibly be a solution.

Nice to hear from you
Nice to hear from you Gordon, there is several points to keep in mind when fitting (or trying) an Enfield Alternator. The Lucas system has always fitted on the three studs with the same angular positioning. although the stud size has increased over the years say from the 60s.
The rotor with Lucas has always had a 19mm hole hence fits to a 19mm crank. (Asside-Some Tiger cubs and some Bantams had 1/2" cranks) this issue was fitted with a steel tube. Do not be tempted to fit a thin stud in a large hole-it will move-disaster will follow. Get specific size studs made. Don't forget the 8th clearance all round between rotor/stator.
Best of luck let us know.

My new 1988 350 Bullet had such an alternator. Open coils, 3 wires, 12 volt, crudely regulated by the light switch.
It lasted nearly 5,000 miles before a stator coil fretted its way through the insulation and shunted itself.
An old 3 wire Lucas alternator did fit in its place.
