Calling any alternator gurus: I have a 14 volt alternator on my O360 with no markings whatsoever. It may have had a sticker on it when new, but if so, the sticker is long gone. No log entries so the alternator may be older than I am. I would like to replace it.

My plane (Tailwind) has a B&C LR3C-14 voltage regulator. I happen to have a new japanese automotive alternator which is identical to the one on my previous plane (an RV6 also with an O360).

Does anyone know about compatibility between an automotive alternator and the B&C regulator? Are aviation alternators somehow different than automotive alternators (electrically)?
Thanks for any info.
