I did Frank's Jap alternator conversion on my bug-i. It is cheap and
easy to do, my total cost was $20 and took a couple of hours, including
shopping at the junk yard and hardware store. If you throw in a 6 pack of cold
beer it could take a whole afternoon.
My car has a amp gauge in it so I could see the difference before and
after. Before with the lights on at idle the gauge would read -15 and at
speed it would read 0 or a little better, without the lights at speed the best
it ever did was +15. Now when I start it, it goes to +15/+30 at idle and
slowly goes to 0 and stays there no matter what I turn on. That is at idle or
speed.
While you don't need to do the conversion just to put in a radio, it is
better than replacing dead generator with a rebuilt one and much cheaper too.
Should make the battery last longer now because the only thing it does is start
the car after that the alternator does it all.
