Illustration 8 g00281837
Circuit breaker
(1) Reset button
(2) Disc in open position
(3) Contacts
(4) Disc in closed position
(5) Battery circuit terminals A circuit breaker is a switch that opens the circuit if the current in the electrical system is higher than the rating of the circuit breaker.A metal disc that is controlled with heat and a contact (3) will complete the circuit through the circuit breaker. If the current in the electrical system is too high, the metal disc becomes too hot. The heat causes a distortion of the metal disc which opens the contacts (2). Open contacts break the circuit. A circuit breaker that is open can be reset after the circuit breaker cools. Push the reset button (1) in order to close the contacts (4) and reset the circuit breaker.
Find and correct the problem that causes the circuit breaker to open.Correcting the problem before running the engine will help prevent damage to the circuit components caused by too much current.
Air Shutoff Solenoid (ASOS)

(5) Air shutoff solenoid that is mounted in the air intake pipe.
The air shutoff solenoid (5) is located in the air inlet system on the top of the engine. When the air shutoff solenoid ("ASOS") is energized, the inlet air to the engine is mechanically shut off. The ASOS can be energized in the following two ways:
The ASOS is energized by the overspeed switch (OS).
The ASOS is energized by the emergency stop switch (ES).Fuel Solenoid (FS)
Illustration 11 g00281970
Fuel solenoid (Typical example)
(1) Diode assembly
(2) Spring
(3) Governor drive
(4) Fuel solenoid
(5) Shaft
Illustration 12 g00293070
(4) Fuel solenoid (FS) that is mounted on the governor.
The fuel solenoid (FS) (4) is located on the governor or on the fuel injection pump of the engine. When the FS is energized, the spring (2) and the shaft (5) will cause the fuel rack to move directly or the fuel rack will move through the governor drive to the FUEL ON position. The FS must remain energized or the fuel flow will be stopped to the engine. 2301A Electric Governor Control
Illustration 13 g00293071
(1) 2301A Electric Governor Speed Control
Illustration 14 g00293069
Electric governor actuator (EGA) (2) and fuel solenoid (FS) (3). The components are mounted on the top of the engine.
The 2301A Electric Governor Control system consists of the following components:
2301A Control
Actuator (EGA)
Magnetic pickup (MPU)The 2301A Electric Governor Control system provides precision engine speed control. The 2301A Control constantly monitors the engine rpm. The control makes the necessary corrections to the engine fuel setting through an actuator that is connected to the fuel system.The engine rpm is measured by the magnetic pickup ("MU"). The magnetic pickup makes an AC voltage that is sent to the 2301A Control. The 2301A Control then sends a DC voltage signal to the actuator in order to adjust the fuel flow.The actuator changes the electrical signal from the 2301A Control to a mechanical output. The mechanical output of the actuator causes the linkage from the actuator
