My system is the Garmin G3X touch.  The engine is the Jabiru 3300, using the Kubota
regulator.  Most times when I take off, the voltage is around 12.5, and shortly
after at full power it will climb to the 14.7 range.  It's at that time,
the tachometer starts acting erratically.

If I pull the power back and the voltage drops a little, the tach will settle to
a smoother reading.

Curt:

The required output of the alternator & ACU to charge a battery is:  13.8
to 14.2 VDC at Minimum of 4 Amps.  If you are not seeing that voltage rand
you are compromising your system and not charging the battery correctly of
fully.

Curt:

What do you mean by "fluctuating"?
Garmin equipment is designed to run up to 36 VDC,so your slightly high
reading of 14.7 VDC is really not an issue for the equipment.  It is
slightly high for charging but still ... acceptable.... Your reading makes
me question what you are using for a VOM?  The accuracy!
Next...  Back to the "fluctuating"...  With the numbers you are posting I'm
thinking the problem is more in-line with the wiring.
