Can Scan Guage II show alternator function?

My 2002 EX has a factory trans. temp guage. I assume thats why it doesnt have an alternator gauge.(no room) Can the scan gauge show alternator function?

My Scanguage II came with a voltage reading for the battery as a standard readout. It reads higher when the engine is on and charging the battery (13-15) as compared to when it is off (11-13).

Not sure if that is what you are looking for.

15 Volts - wow, I do need a new alternator. Mine will get up to 13.6 after a few minutes of driving at speed - but goes down from there.

Scan Gauge will read battery voltage which tells you what your alternator is doing.

Alternator went completely this week - got the stock replacement from DBElectrical.
puts out 14.2 just off idle and sits between there and 14.5 all day - or at least for the 500 mile trip to the Catskills this weekend.
