A voltmeter measures
electrical system pressure in volts. A voltmeter only needs to tap
into an electrical circuit (we are tapped into the power to the
Fuel Gauge). Voltmeter installation is easy, quick, and safe: It
hooks up to a fused, ignition-switched "off/on" source.
The voltmeter directly
measures the result of charging-system performance. With normal
alternator/voltage-regulator function, battery voltage is maintained
at 14.0 to 14.5 volts-and this is reported directly by the voltmeter.
In the event of alternator-system failure, voltage will be low and
continue to drop as the battery discharges. In the event of an "overcharge"
condition, the voltmeter will climb above its normal zone.

NOTE:
Fuel Gauge points straight up because it has power but no signal.
