My 3 gauge setup consists of oil pressure, Volts, and water temperature
(Equus electrical gauges).  I have the Voltage gauge running to a spdt
switch so I can switch between aux battery or main battery with a center
off position.  The main battery doesn't need the center off as it senses
12 volts from an "ignition on" source.
