Tachometer: Description and Operation
Description
DESCRIPTION
A tachometer is standard equipment on all instrument clusters. The tachometer is located to the right of the speedometer in the instrument cluster. 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 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 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, gray and black against a black field except for several red graduations that designate the red line area 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 graphics retain their unilluminated colors and appearance. The orange
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.
