Voltage Gauge Readings...Help!

[Scott Forman]

Is the reading on the engine voltage gauge of any use when the engine
isn't running?

I have four 2-month old T-105's and an IntelliPower converter/charger
with the Charge Wizard option that makes it a three-stage charger.
My engine voltage gauge seems to work accurately. The dash amps
gauge does not work at all, I cannot find why. The amps gauge in the
step well seems to work accurately.

Enough background...does the voltage gauge reading matter when
parked? When on shore power or gen, it shows accurately the voltage
being delivered to the bat's whichever stage the charger is in.
Likewise, the step well amp gauge will show charging as appropriate.
When in "dry" mode, though, the voltage gauge will fall down to 12 or
even slightly below within a matter of a few minutes of the power
being disconnected without any 12v items on. The step well amps gage
does NOT show discharge at this point, and when power is reconnected,
the indicator lights on the charger will still reflect fully charged
batteries.

So...is this voltage gauge reading showing me something that matters
or not? And if it is irrelevant when parked, is there a way I can
determine how far down the bat's are without pulling out the
multimeter?

Thanks
