(1) Glow Plug - The alert indicator will light when the engine start switch key is turned to the Glow Plug position.
(2) Alternator Indicator Light - The alert indicator comes on when the engine start switch key is turned to the ON position. The alert indicator goes off after the engine is started. The alert indicator will light when there is a malfunction in the electrical system. If this alert indicator comes on, the system voltage is too high for normal machine operation or too low for normal machine operation. If electrical loads are high and the engine speed is near idle, increase the engine speed to high idle. This will generate more output from the alternator. If the alert indicator for the electrical system turns off within one minute, the electrical system is probably operating in a normal manner. However, the electrical system may be overloaded during periods of low engine speeds. If an overload occurs at low engine speed you should perform one or a combination of the following actions.
Increase the engine speed.
Lower or turn off the heater fan.
Turn off any auxiliary electrical equipment.If the alert indicator does not turn off, consult your Caterpillar dealer.
(3) Engine Oil Pressure Indicator - The alert indicator comes on when the engine start switch key is turned to the ON position. The alert indicator goes off after the engine is started. If the engine oil pressure is insufficient, the alert indicator will come on. If the alert indicator comes on, stop the engine immediately and check the engine oil level. Make any necessary repairs before starting the engine again. In cold weather, the indicator may remain on for more than ten seconds after the engine is started.
(4) Air Cleaner Indicator - If the air cleaner element is clogged, the alert indicator will come on. If the indicator comes on, stop the engine immediately. Clean the element or change the element.
