2-1/16 GS Voltmeter Gauge - 8-18

The AutoMeter 2-1/16 GS Voltmeter Gauge (8-18V) is a precision electrical monitoring instrument designed for vehicles and equipment requiring real-time battery and charging system voltage assessment. This analog gauge addresses a critical need for operators and technicians who depend on immediate visual feedback to diagnose electrical system health and prevent unexpected power failures. Whether used in classic cars, diesel trucks, marine vessels, or off-road platforms, this voltmeter delivers reliable voltage monitoring in a compact, universally compatible format.

Built with AutoMeter's full-sweep mechanical movement technology, the 2-1/16 inch diameter gauge provides smooth, responsive needle action across its 8–18 volt range, allowing users to detect subtle charging anomalies before they become critical failures. The black face design ensures excellent readability in varied lighting conditions, while the electric analog display eliminates dependency on digital readouts that can fail during electrical distress. Constructed to withstand vibration and temperature fluctuation typical of engine compartments and harsh environments, this gauge integrates seamlessly into dashboard installations and aftermarket gauge clusters without requiring complex wiring modifications.

Professionals, restoration enthusiasts, and fleet operators benefit most from this voltmeter's durability and straightforward installation. It pairs effectively with stock and performance electrical systems, providing baseline voltage reference for alternator output verification, battery condition assessment, and charging circuit troubleshooting. The compact 4.85 x 4.5 x 5.05 inch footprint allows flexible mounting in factory gauge openings or custom panels, making it ideal for both OEM restoration and modern performance builds seeking authentic analog instrumentation and reliable electrical diagnostics.
