[. . . ] 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 are illustrated in figures 1 through 4. 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. Kits that simplify the actuator mounting and connection are available for several engines. 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 air lines and electrical wiring as illustrated. OPERATION The High Idler receives its power from the ignition switch and functions only when the ignition switch is either "ON" or in the ACC. High Idle is automatically disabled under any of the following conditions: 1. 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. 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.
