BN1 alternator conversion

[davidtr6]

I want to use a modern alternator on my BN1. Crank and water pump pulleys use wide belt. I have wide pulley from generator. Pulley shaft hole is 5/8 in.
Is there an alternator with a 5/8 in shaft for the original style pulley? What have others used to convert to an alternator? Help appreciated David

Also want to use the expernal regulator, not an internal regulator

This is the best idea

Look at this on eBay:

45 Amp dynamo to alternator conversion

it is regulated so all you do is change to negative earth and run a wire to the batter side of the starter solenoid mad leave everything as is. Dead simple.

David--

I bought a Leece-Neville/Prestolite universal alternator which came with a two-piece pulley that I shimmed to accept a wide belt, thus saving me having to replace the other pulleys. Also, the alternator has an external regulator which would make it much easier to service, though I have been running it for about 60K miles and have yet to need the spare regulator. I believe it is a 75 amp unit and if you are interested I can try to find a model number or send a photo.

I installed a Gener-nator on my 62 BN-7. I don't know if the BN-1 has a different generator than the 3000, and if different, whether one could be retrofitted but it might be worth looking at their website.
