Stand Alone Speed Control Voltage/Resistance Test Connections

Figure 1:




Refer to Figure 1 and locate Circuit 203 (Orange/light blue). It is used ONLY on the 1991 Lincoln Town Car with electronic cluster. This circuit connects the speed control amplifier to a speed control "set" indicator which is located at the lower edge of the electronic cluster center section. The voltage at circuit 203 is normally 5.0V (speed control not set) and less than 1.0V when the speed control is set. Grounding circuit 203 pin will light the cluster display. The SPEED CONTROL display will light only when a set speed is being maintained and when using ACCEL or RESUME. The display will turn off when braking, using OFF or COAST, with the ignition off.
