Ken,
I am not aware of any. I presume by examining a diagram of the
rectifying diodes in an alternator that you might be able to determine
whether there is a path for excitation voltage (a Sneak Circuit) other than
the terminal to the field coil. Another way might be to apply B+ voltage to
the altenator output (but not the field coil) and then with a voltmeter
determine whether there is any voltage showing up at the field coil
terminal. If voltage shows up then that would indicate to me that there is a
path for voltage from the output of the alternator to the field coil
internally, so it would be self exciting.
Thats my best hack at your question.
Ed
Is there any way to determine if an internal reg
alternator will act like yours without spinning it up and testing it?
