52mm Analogue Voltmeter

- / per
Type: analogue voltmeter
Size: 52mm
Power: 12V or 24V
24V version: stepper motor for a steady needle
Waterproof rating: IP67
Face: black or white
Bezel: black or white plastic, or 316 stainless
A 52 mm analogue voltmeter for monitoring battery and system voltage at a glance. Voltage is the quickest read on the health of an electrical system: with the engine running and charging, a healthy 12V system sits at roughly 13.8–14.4V (a 24V system reads double). A reading that won’t climb above about 13V, sags under load, or sits low points to a flat battery, a poor connection or a charging fault.
The 24V version uses a stepper-motor movement, so the needle stays steady rather than drifting.
A voltmeter shows the voltage; to see the current actually flowing in and out as the system charges or discharges, pair it with the 52mm Ammeter. Available in a choice of face and bezel finishes, for 12V or 24V systems.
The gauge has a 4-pin connector — there is no sender; the voltmeter reads the supply voltage directly:
Blue — 12V negative (ground)
Red — 12V positive (fused, via the ignition or a separate switch)
Orange — red backlight
Yellow — amber backlight
Connect either the Orange or the Yellow wire for backlighting — the wire colour matches the backlight colour. The backlight is dimmable.
Runs on a 12V or 24V supply directly — no voltage regulator or dropping resistor is needed.
1. Cut a 52mm (2 1/16") diameter hole in the panel. You will need a minimum clearance of 55mm (2 3/16") behind the panel to fit the gauge. The panel can be 1–20mm thick.
2. Remove the fastening ring, insert the gauge through the panel from the front, then fit and tighten the fastening ring from the rear.
3. Connect the wiring as shown in the wiring diagram, selecting either the Orange or Yellow wire for your preferred backlight colour.
4. Securely connect the plug into the port at the back of the gauge.
