| Subject: | alternator field current |
There have been a few discussions here about alternators tripping their
5A field breaker, but consensus has been that properly operating field
windings don't draw more than 5A. 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.

Here's a data sheet:

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....)
