My 1980 B-55 has uneven load distribution on the two alternators, with the
right side consistently reading around 15% lower than the left.

Is this an indication of a problem with the alternator like a bad diode, or
is this normal operating behavior?

I had a similar problem with a Seneca. Except is was more like 80/20.
Turned out to be the voltage regulators being set higher on one
alternator than another.
