INTRODUCTION

The High Idle System consists of a model 091-84-005 Engine Idler and a model 091-84-004
Voltage Monitor. The system permits a vehicle operator to increase engine RPM to obtain
more alternator output. RPM may be increased manually from the Engine Idler or automati­cally from the Voltage Monitor when the system voltage drops below the threshold. In order
to move the throttle mechanism or interface with electronic controlled engines additional
components are required.

DESCRIPTION

ENGINE IDLER:
This module is the heart of the system. It interfaces with the Brake Pedal Switch, the Voltage
Monitor, Neutral Safety Switch and the output solenoid valve or relay. 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 HIGH indicator is illuminated.
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. Pipe the solenoid valve output to the
actuator as illustrated in figure 1 or figure 2. Install wiring as shown.

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. position. High Idle is automatically disabled
under any of the following conditions:

1. Operator depresses the "OFF" pushbutton on the Engine Idler

2. Operator depresses the brake pedal

3. Operator places the transmission into Drive or Reverse

4. Operator turns off the ignition switch
