A new Rotunda #007-00013 speed control tester is
now available for functioning and diagnosing all Ford
factory installed speed control systems from 1974
through 1985 model year for both passenger cars
and light trucks.
The tester (Figure 5) works on vehicles with all combinations of control switches, transmissions, speedometers (electronic and mechanical), brakes,
clutches, etc. With three modes of operation (Automatic, Single Scan, and Scan Probe), the mechanic
can pinpoint any failure including wiring, vacuum lines, switches, servos, etc.
The tester includes a manual with its own specially developed "diagnostic trees" for identifying any failed or marginal part in the speed control system.
Service technicians with little or no experience with speed control systems can use this tester to efficiently service the systems.
