GENERATOR START-UP PROCEDURE

4.Depending on the temperature of the coolant (cold weather conditions), the pre-heat lamp (Figure 42) will light (ON) and remain on until the pre-heating cycle has been completed. After completion of the pre-heating cycle, the light will go OFF and the engine will start up automatically.

8.The generator’s AC-voltmeter (Figure 46) will display the generator’s output in VOLTS.

5.Once the engine starts, let the engine run for 1-2 minutes. Listen for any abnormal noises. If any abnormalities exist, shut down the engine and correct the problem. If the engine is running smoothly, place the engine speed switch (Figure 43) in the HIGH (up) position.

Figure 43. Engine Speed Switch (High)

6.Verify that the Engine Running status LED on the MPEC unit (Figure 44) in ON (lit) after the engine has been started
