Speedometer Head: Description and Operation
How the Circuit Works
When the ignition switch is in ON (II) or START (III), battery voltage is supplied through fuse 25 to the gauges in the gauge assembly.
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.
