Speedometer Head: Description and Operation
Description
DESCRIPTION
A speedometer is standard equipment on all instrument clusters. The speedometer is located in the center of the instrument cluster, between the
tachometer and the minor gauge set. The speedometer consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry and a
fixed 210 degree primary scale on the gauge dial face that reads left-to-right either from 0 to 120 mph, or from 0 to 200 km/h, depending upon the
market for which the vehicle is manufactured. Each version also has a secondary inner scale on the gauge dial face that provides the equivalent opposite
units from the primary scale. Text appearing on the cluster overlay above the hub of the speedometer needle abbreviates the unit of measure for the
primary scale (either MPH or km/h ), followed by the unit of measure for the secondary scale.
The speedometer graphics are black (primary scale) and blue (secondary scale) against a white field, making them clearly visible within the instrument
cluster in daylight. When illuminated from behind by the panel lamps dimmer controlled cluster general illumination lighting with the exterior lamps
turned ON, the white gauge dial face appears blue-green with the black and blue graphics silhouetted against the illuminated background and the red
gauge needle still appears red. Gauge illumination is provided by an integral electro-luminescent lamp that is serviced as a unit with the instrument
cluster.
The speedometer is serviced as a unit with the instrument cluster.
