I found in a wonderful resource I had not seen before,

http://www.practical-sailor.com/news...Questions4.pdf

a reference today to a design in The 12 Volt Doctor's Practical Handbook
for an alternator controller. It's not an easy book to get in the UK and I
wonder if anyone who has a copy would be able to tell me more about the
section of the book that deal with this project, or perhaps scan and mail
it if it's not too long.
