1. Why would you disconnect the battery to replace the alternator?

I suspect it was in an attempt to reseat all connections that could
contribute to the problem. I had already done this as well as "moving" all
of the alternator mounting bolts. I didn't try any magic juice, however.

A wise move...

And I always pull the battery ground before I swap an alternator or
such. Then, when I drop the wrench or such; that precaution cuts
down on the "sparky-do's" as an old cow orker used to called it.

I've no doubt it's now a Terrorist Act to take an aircraft alternator
to an autoparts store for testing; but if it were from an airboat,
[YES, that's it, an IO-540 in an airboat....] then you might go that
route. The trouble is, will Al Autozone know how to hook up an
alternator sans regulator?

I wonder if aircraft will ever get internal regulators as cars have
had for 20+ years. It really cuts down on the number of wires to
come lose & cause weird grief...
