Default Voltage variation

...Under what load do yue see 14.4? How long after starting?


That's 13.4 or .5 in cruise flight, with two nav/coms and strobes on.
Probably turning 2300 RPM, say, ten minutes after launching.


What is the voltage at moderate RPM with no loads,
& with the JPI on so you can see its reading?
With every frigging thing on, including the Jacuzzi and the landing
lights? [We'll skip cycling the gear....]


Dunno. I'll have to record these, next time I fly.


The sealed battery is maybe a year old. Cranks just fine.



OK, I asked "how long" because the voltage post-cranking may
be lower.

The real question is: what've the voltage at the battery terminals?
But that's hard to measure in flight...
