250 Alternator on a 160 Junior

[gregwils]

I have a few spare 250 alternators that I am not using at the moment. I was thinking about putting one of them on a 160 Junior, I believe it should fit. The output on the Junior alternator is really low, IIRC it's 24 W. A 40W or 60W 12v system would allow the lights to actually work. Is there any reason this a bad idea?

Hi all, sorry to junp in on this thread but any information that comes up may be useful. I have a an Elite with the 24 watt alternator and the thought ocurred to me also that a later higher output stator could be fitted, so I obtained a later one with 4 coils and a rectifier regulator for 6 volts which is rated for 200 watts. My problem is that I am not an electrical wizard, but it's obvious to me that there is an ground connection on the 4 coil stator which would not be required when connecting to the rectifier regulator which has the usual 2 connections from the stator. So would it be possible to rewire the stator to provide a suitable output to the rectifier regulator? I don't know if there would be any issues with output phases if rewired?

Hi, I have the 60 watt alternator on a 250. Many years ago I modified it the remove the coil earths and link the coils in a more conventional way and fit a modern rectifier/ control box. This has worked for many years ,however Its possible that there are some benefits with the orriginal and somewhat unusual design. There has been a vast amount of posts in the past about the pro's and cons of the orriginal design, most of which went completely over my head . Perhaps someone could give us a comprehensible conclusion to the saga that would be usefull to us ignorant dimwits.

Probably not the only one thinking it would be great to have Dew Cat Tee Bob back at this moment. I’d guess some archives may assist ?

And I swear I will be getting my 250 and 350 going soon. That’s why I don’t sign in much. But much enjoy a daily check in. Cheers!
