I have purchased and owned a lot of alternators over the years. I will say, do not believe everything they print in catalogues about their fancy alternators. Many manufacturers make claims that just aren't true....Had more than one argument with big name brand "Sales" artists...I won't bore you with all the details.....But I will give you a link to the best 1-wire alternators to date I have found:
https://www.cvfracing.com/search/searchresults/?search_query=alternatorIf you want an alternator that can do double duty, and keep up with all the electrical load of dual fans, elec water pump, fuel pump and four head lights...Purchase one of their 140amp alternators....Hands down, charges at idle with a hell of a load on it....At 10 or 11 pounds, these kick but at low rpm compared to anything else I have run. Highly recommend them.
