[. . . ] The Engine Idler has a High Idle "ON" and "OFF" pushbuttons on its front face allowing the operator to switch in and out of HIGH IDLE when the vehicle is in Park or Neutral. An LED indicator on the front face is illuminated when the engine is in HIGH IDLE. VOLTAGE MONITOR: This module interfaces with the Engine Idler module to activate the high idle system whenever the detected voltage drops. [. . . ] Three LED's indicate High, Low or Normal battery voltage. When the battery voltage is above 15. 6 volts D. C. The LOW battery voltage indicator illuminates when the battery voltage is below 12. 5 volts. At this time a signal is sent to the Engine Idler module automatically placing it in high idle. This occurs only if the transmission is in Park or Neutral and the brake pedal is not depressed. INSTALLATION Typical installations on gasoline and diesel engines are illustrated in figures 1 and 2. Mount actuator and solenoid valve in an appropriate location and connect the actuator output to the throttle mechanism. (Note: The actuator and solenoid valve must be purchased seperately. Be certain that the ball chain or other coupling does not restrict throttle motion at full closed throttle or wide-open throttle. Connect solenoid valve input to a source of vacuum for gasoline engines or pressure for diesel engines. Depress the ON switch on the Engine Idler and adjust the coupling to the actuator and the stroke to obtain the desired engine RPM. Recheck by turning the unit ON and OFF a few times. Load the electrical system by turning on the headlights, area lights or other accessories. Note that when the voltage drops below 12. 5 volts, the following occur: a. The Low indicator on the Voltage Monitor illuminates. The indicator on the Engine Idler illuminates. The High Idle System is active and the engine is speeded up. CAUTION FORD INSTALLATIONS FORD, in many installations uses a starter solenoid which has one side of the coil grounded. The neutral safety switch is then placed in the supply side of the solenoid coil. This configuration creates a considerable voltage spike when the vehicle is started. [. . . ] This configuration creates a considerable voltage spike when the vehicle is started. A diode must be placed across the starter solenoid in these installations to prevent damage to the engine idler. See the appropriate wiring diagram for diode installation details.
