Tachometer

The Tachometer displays Engine speed in Revolutions Per Minute (RPM). Voltage pulses from the Electronic Ignition Control Module (V6 VIN K) or the Powertrain Control Module (V8 VIN G) are interpreted by solid state logic circuits within the Cluster. The solid state circuits process the pulses and put out a signal that drives the pointer of the meter. The pointer is moved with magnetic fields created from coils within the Tachometer.
