Speedometer Head: Description and Operation
Speedometer
When the ignition switch is on ON (II) or START (III), battery voltage is supplied through fuse 1 to the gauges in the gauge assembly. The gauge circuit
is grounded at G404.
Speedometer and Odometer
The odometer and speedometer drive circuits receive pulses from the Vehicle Speed Sensor (VSS). The pulse rate increases as the car accelerates.
The frequency and duration of these input pulses are measured and displayed by the speedometer, odometer, and tripmeter.
