Output State Check

The Output State Check is used as an aid in servicing output actuators associated with the EEC-IV system. It allows you to energize and de-energize most of the system output actuators on and off on command.

This mode is entered after all codes have been received from KOEO and CONTINUOUS SELF-TEST. At this time, leave SELF-TEST activated and depress throttle. Each time throttle is depressed and released, the output actuators will change state (go from on to off, or off to on).
