Well nothing just now, but in the future it will! Before the engine is started we need to turn the Master Switch to EO (engine only) and we will see a lamp, the "Engine Stop Indicator", illuminate on the dashboard and we should hear the Fuel Pump and the Lubrication oil Priming pump start running from the starting batteries. The fuel pump will always be running as it has to raise the fuel from the under frame tanks to a header tank in the engine room. Since the engine has its own higher pressure mechanical drive oil pump the priming pump is turned off automatically when the engine starts under its own power.
To allow proper priming of the oil we must allow 30 seconds to pass before we press the start button and when we do a lot of things happen. First, a strange thing happens to the Main Generator, normally used to produce 600 volts for traction and heating, it turns itself into a starting motor! A contactor is activated and the starting battery current flows through the Main Generator, which turns the engine over. At the same time the first Engine Governor solenoid is activated which sets the Engine Governor and a mechanical fuel pump forces a spray of fuel from a Fuel Injector which is ignited in the hot compressed air in the cylinder. And the engine starts to turn under its under its own power. Few!
The control system determines the engine to be running when the mechanical oil pump gets the lubrication pressure above 27 PSI and a pressure switch activates. At this time the "starting motor" is deactivated, the engine stop indicator lights go out, the Auxiliary Generator starts, the Air Compressor motor starts, the batteries start to be charged and by now the exhaust gasses are driving the turbo charger and the air intake is at pressure. And now the Engine Governor gets into its characteristic slightly erratic control of the engine speed. Ah I can hear it now, Magic!
