Dan,
Do you want to measure current into/out of the
battery, or the current output of the alternator? In the case of measuring
alternator output you'd want an ammeter that can measure the rated output of
your alternator. I'm guessing that's at least 60A, probably more.
I'm not that familiar with IVP electrical loads, but I've seen a Legacy
alternator put out over 50A with everything on the panel turned on, landing
lights, and the gear in transit. By the way, if you have two
alternators you really should have a shunt, or Hall effect sensor (whichever
your ammeter uses), on each alternator output and either two meters or a
way to switch the meter between the two alternators.
In the case of measuring current into/out of
the battery you'd want an ammeter that can measure the maximum electrical
load of your plane (but not the starter current), which the battery would have
to supply if the alternator is off line.
