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 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. Consult KECO sales
Department). 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. 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

TEST PROCEDURE

1. With the transmission switch in PARK turn the ignition switch the Accessory
position. The LED on the Engine Idler should remain OFF.

2. Press the "ON" switch on the Engine Idler. The LED on the Engine Idler should turn
ON.

3. Move the transmission to Drive or Reverse. The LED on the Engine Idler should
turn OFF.

4. Place the transmission in PARK and press the "ON" switch to turn the LED ON
again.

5. Depress the Brake Pedal. This should turn the LED OFF.

NOTE:

Steps 1 thru 5 are valid only if the battery voltage is greater than 12.5 volts. If less than

12.5 volts, the Voltage Monitor may turn on High Idle system.

6. Start the engine and allow it to warm up with the transmission in PARK mode.

7. 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.

8. 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.
b. The indicator on the Engine Idler illuminates.
c. The High Idle System is active and the engine is speeded up.
