ETOPARS Car Vehicle 2inch 52mm Pointer Oil Temp Temperautre Gauge Meter Kit

Gauge read 10psi without being installed. Should not have passed quality control. Returned.

as described easy to fit would buy again from seller

Oil pressure sending units can have either one wire or three wires, and the choice depends on the type of sensor and its intended application. Here's an explanation for both:Single-Wire Oil Pressure Sending Unit:A single-wire oil pressure sending unit is a basic sensor. It typically has just one wire that connects to the gauge or warning light in the vehicle's dashboard.These sensors are often used in older vehicles with simple warning lights for oil pressure. When the oil pressure drops below a certain threshold, the sensor grounds itself (completes the circuit), which triggers the warning light to come on.They are less precise than three-wire sensors and mainly provide an "oil pressure low" warning.Three-Wire Oil Pressure Sending Unit:A three-wire oil pressure sending unit is a more advanced sensor.It typically has three wires: one for power (usually 12V), one for ground, and one for the signal.The power and ground wires provide the sensor with the necessary electrical supply, and the signal wire sends a variable voltage signal to the gauge.These sensors are commonly used in modern vehicles with oil pressure gauges that display real-time pressure levels. The variable voltage signal allows for a more accurate representation of oil pressure.This gauge is designed to work with a three-wire oil pressure sensor and a single-wire sensor was provided;The single-wire sensor typically functions by grounding itself to trigger a warning light when the oil pressure drops below a certain threshold. Since your gauge expects a variable voltage signal from a three-wire sensor to display real-time pressure levels, it may not interpret the single-wire sensor's signal correctly, resulting in a reading of 100%.

Messgerät defekt kein Schalter für zylinderauswahl. Zeiger steht auf 6000 Umdrehungen.

Reçu sans le bouton de sélection de cylindre arrière et aiguille bloquée à 6000trs

Lo he instalado tal como pone en las indicaciones y no funciona, no se puede seleccionar el número de cilindros en el tacométro.

Heel mooi toestel, betroubaarheid kan ik helaas nog niets over vertellen, wel dat het zeer gevoelige toestellen zijn. Denk dat ze vrij correcte waarden geven.
