OK Neil.

You find it in the article.

My Deutsch is far too rusty to find it in the article. ;-)

POH - Under - abnormal operating procedures - 4B.7 STARTING ENGINE
WITH EXTERNAL POWER - #13 Opposite engine ..... START WITH NORMAL
PROCEDURE

That is it.

That's fine for starting the engines, but that isn't the only issue, is
it?

Is there nothing in the POH about the electrically powered items
(landing
gear, FADEC, etc.)? If there is, it shouldn't require an EE degree to
realize that one should be concerned about the condition of the
batteries,
charging, etc. if one has to "jump start" the engine, or to realize that
something critical is in need of attention.

Maybe I'm just an overly cautious type. ;-)

No, you are not overly cautious. Every pilot should be taught that if
the battery is dead and you start the plane with external power, the
first thing you check is to see if the alternator(s) is charging. If it
isn't, either the alternator is broken or the battery did not excite
the alternator.

Now, if the excitation system did not excite the alternator, why didn't
the remote starting system do it? It should have. I would want a look
at the power cart, its cables, and the wiring to the port on the
airplane. In fact, especially the latter, as it could provide a clue as
to why the excitation battery died in the first place.

Actually, it may be possible to start some older airplanes on external
power, disconnect the power cart, and then not have enough voltage to engage
the alternator solenoid. I no longer recall the exact circumstances, and
don't have a manual available, but I believe that it was even possible to
induce the problem on a plain old Cessna 172.
