VDO SingleViu 52mm (2-1/16") Ammeter - 100 AMP

The VDO SingleViu 52mm (2-1/16") Ammeter - 100 AMP is an essential electrical system monitoring instrument for any serious vehicle builder or restorer who needs real-time charging system diagnostics. Whether you're customizing a classic hot rod, building a restomod, or troubleshooting electrical gremlins on a modern swap, this precision ammeter provides the critical feedback required to verify alternator output and battery charging performance. VDO's SingleViu series has become the industry standard in aftermarket gauges because it delivers both aesthetic integration and technical reliability in a compact, easy-to-read format.

Built with analog dial technology and a robust 100-amp measurement range, this ammeter uses precision needle movement to display charge and discharge rates with immediate visual feedback—something a warning light simply cannot replicate. The 52mm (2-1/16-inch) gauge diameter fits seamlessly into standard aftermarket gauge pods, custom dashboards, and pillar mounts, making installation flexible for both tight engine bays and custom instrument clusters. VDO's sealed construction protects against vibration and environmental contamination, critical for reliable operation in high-performance or vintage vehicle applications where electrical stability directly impacts ignition timing and overall engine management.

Technicians and enthusiasts routinely specify this ammeter for EFI conversions, alternator upgrades, and electrical diagnostics where monitoring actual charging amperage prevents battery drain, alternator failure, and accessory load issues. The 100-amp capacity suits everything from mild street machines to high-amperage modern alternator installations, and the straightforward shunt-style connection integrates directly into your charging circuit without complex wiring logic. Installation requires only a dedicated battery-to-alternator circuit connection and proper grounding—making this an ideal upgrade for any vehicle undergoing electrical system modernization or repair.
