|Auto Throttle 1||Voltage Monitor||Engine Idler||Pressure Actuator|
|An Automatic Engine Idler control. When the battery voltage is low, the unit switches to high idle.||Voltage Monitor will automatically turn "ON"
high idle when low
voltage is sensed.
|Engine Idler which
contains "ON" and "OFF" switches to permit manual control of high idle.
|An Actuator which pulls
the throttle mechanism to increase the engine speed. The actuator is air operated.
|Pressure Actuator||Solenoid Valve||Vacuum Actuator||Vacuum Valve|
|Actuator which pushes the throttle mechanism to
increase the engine speed. The actuator is air operated.
|A Solenoid air valve which controls the air pressure supplied to the actuator.
||Actuator which pulls the
throttle mechanism to obtain increased engine speed. The actuator is vacuum operated
|Solenoid Vacuum Valve
which controls vacuum supplied to the actuator.
|Interface relay, connects the Engine Idler to the ECM.
