It has been my experience that the voltage has to get REALLY low to effect the gauges, there are internal voltage regulators in the gauges so that battery voltage swings will not produce much variations. What does your dash mounted voltmeter do?

HOWEVER--

Bad ground connections can and will cause gauges to go wild, the type of changes you describe are wild.

When my alternator went bad, the battery voltage went as low as 10 volts and I had a very slight meter reading change, temp changed only a few degrees, oil nothing and the fuel gauge slightly.
