This manually-operated control panel is equipped with a key switch, an RPM gauge, a PREHEAT and START
button, and an instrument test button along wtth a low oil pressure/high water temperature alarm. The RPM
gauge is illuminated when the key switch is turned ON and remains illuminated While the engine is in opera-
tion. The key switch and the three buttons serve the following functions:
1. Key Switch: The Key Switch provides power only to the instrument panel cluster. Refer to the "STOP-
PING PROCEDURE" section of this manual, page 28.
2. PREHEAT: The PREHEAT button activates the alternator's regulator, the engine's glow plugs, and bypas-
ses the engine's oil pressure alarm switch. In addition, this button energizes the START button.
3. START: The START button, when pressed, energizes the starter's solenoid which cranks the engine.
This button will not operate electrically unless the PREHEAT button is pressed and held at the 81me
time.
4. Test Button: The Test Button, located above the key switch, tests the alternator, the oil pressure, and
the water temperature control circuits. When this button is pressed, the alternator, the oil p""ssure, and
the water temperature indicator lights illuminate in addition to sounding the alarm.
