Just stumbled upon an interesting data point that's 'new to me'. Apparently, there may be some older models that do. Someone on another forum asked about how to hook up a Transpo V1200 adjustable regulator. Turns out, there's an old thread here on AEC about it. http://www.matronics.com/forums/viewtopic.php?t=46713&sid=9b0b3a2dcfc6958ef0d291d283abd4b9 Here's a data sheet: http://estore.waiglobal.com/productdatasheets/PD0570_0.pdf Since it's adjustable, I thought it might be an inexpensive option for primary and backup alternator duty. According the data sheet, field current is '10A typical; 20A max'. I went trolling ebay looking for a deal on it, and stumbled upon this: https://www.ebay.com/itm/PREMIUM-ADJUSTABLE-EXTERNAL-VOLTAGE-REGULATOR-CHRYSLER-DODGE-PLYMOUTH-1970-87/143191553879?hash=item2156e1b757:g:jpAAAOSwfRZcnWcx a completely different model that is 'for 7A rotors'. So apparently, there are some alternators out there in the wild that could indeed draw more than 5A field current. No immediate reason for posting this; just found it interesting. (Of course, I might be the last guy to discover it....)
