As part of the diagnosing of the charging problems with the JPS (now completely cured) I found that there were multiple contributing factors in addition to an intermittent failure in the stator. One of the things that weren't quite "right" was the regulator.
I have alwways used Bosch (Australia) RE57 and RE55 external regulators, they have provided sterling service and have proved to be reliuable as a hammer (this is the first failure I have ever experienced in one) but unfortunately when I went to buy one I found that they have been out of production for a number of years and those few that remain have silly asking prices.
I bought a Euromotorelectic adjustable device and it works happily, but I am not using it.
In the course of my searching I found these interesting Chinese devices and at approximately $AU10 each I couldn't help myself. I am running one now and it seems to provide a very steady 13.9 to 14.2 volt regulation, annd it has a neat little LED to let you know it is working.
Put the part number into eBay if you are interested.
