Tachometer - Description

DESCRIPTION





A tachometer is standard equipment on all instrument clusters. The tachometer is located to the right of center in the instrument cluster, between the speedometer and the coolant temperature gauge. The tachometer consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 185 degree scale on the gauge dial face that reads left-to-right from 0 to 6. The text RPM X 1000 imprinted on the cluster overlay directly above the hub of the tachometer needle identifies that each number on the tachometer scale is to be multiplied by 1000 rpm.

The tachometer graphics are white against a black field except for several red graduations at the high end of the gauge scale, making them 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 white text and graphics still appear white and the red graphics still appear red, but an inner secondary scale-like graphic appears blue-green. The red gauge needle has internal optical illumination. Gauge illumination is provided by Light Emitting Diode (LED) units soldered onto the instrument cluster electronic circuit board.

The tachometer is serviced as a unit with the instrument cluster.
