Not neccessarily. *You'd have to check the equipment list - if only 1

Mirage which has 2 alternators installed lists 1 as required

windshield, lift transducer, etc).

Yup, no disagreement. I just meant that an inop gauge (in addition to
a legal, working one for the same tank) doesn't automatically violate
91.205b9.

It would if that working guage isn't TSO'd as a primary guage and/or
two factory installed guages are called out by the equipment list
and/or KOEL.
