ABSTRACT:
A portable self-contained instrument for testing the idle speed control system in an automotive engine includes LED indicators for displaying engine computer output pulses to the idle speed stepper motor, and a multi-pole rotary switch connected to an internal battery for deriving the voltages necessary for exercising the stepper motor. A mode switch allows normal engine operation while monitoring the computer output on the LEDs, or connects the rotary switch for controlling the stepper motor while disabling the computer.
