Description - RHD: Tachometer

A tachometer is standard equipment on all Dodge premium and Chrysler instrument clusters. There is no tachometer in the Dodge base instrument cluster. On Dodge vehicles, the tachometer is located to the right of the speedometer in the instrument cluster. On Chrysler vehicles, the tachometer is located just to the right of center in the instrument cluster, between the speedometer and the temperature gauge. The tachometer consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 230 degree scale on the gauge dial face that reads left-to-right either from 0  to 7  for vehicles with a gasoline engine, or from 0  to 6  for vehicles with a diesel engine. The text RPM X 1000  imprinted on the cluster overlay directly below the center of the scale identifies that each number on the tachometer scale is to be multiplied by 1000 RPM.

On Dodge vehicles, the tachometer graphics are gray and black against a white field except for several red graduations that designate the red line area at the high end of the gauge scale. On Chrysler vehicles, the tachometer graphics are gray and black against a silver field except for several red graduations that designate the red line area at the high end of the gauge scale. In each case, the graphics are clearly visible within the instrument cluster in daylight. When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting with the exterior lamps turned ON, the Dodge gauges all retain their unilluminated colors and appearance, while the Chrysler gauge fields acquire a blue-green appearance from the blue-green colored electro-luminescent lighting.

The Dodge premium and Chrysler clusters use black gauge needles, and are not illuminated. These clusters are illuminated by an integral electro-luminescent lamp, which illuminates the gauge field and causes the gauge graphics and gauge needle to appear silhouetted against the field when the exterior lighting is turned ON.
