System Descriptions

Engine Control System (cont)
Start Position. Moving the Off/Run/Start switch to the Start position allows +12 volts to flow the same as in the Run position. In addition, +12 volts flows through the harness (white wire) to the start relay (located on the top of the generator, by the start motor). With +12 volts applied, the relay energizes and the internal contacts close. The start motor begins to crank the engine and the internal oil pump begins to develop oil pressure and "floods" the bearings with oil.
 
When the oil pressure reaches 15 psi, the oil pressure switch closes. +12 volts then goes to the Fuel Control Valve, energizing it, and back to the panel through the harness (blue wire) to illuminate the oil lamp.
 
As soon as the Fuel Control Valve is energized, high pressure fuel is delivered to the injector, and the engine will start. The oil pump continues to deliver oil to the bearings and the oil pressure switch will stay closed. The hourmeter on the panel will also operate.
 
 
Safety Stops
As described previously in the Off/Run/Start switch sequence, the entire switch and control system operates in series. If any one of the three switches opens, the circuit is broken and the engine will stop. Turning off the ship's 12 volt power will also stop the engine.
 
Understanding the Lamps
All Lamps Out. If the water temperature switch opens, because of high coolant temperature, the engine will stop and all of the lamps will go out.
 
Exhaust and Oil Lamps Out. If the exhaust temperature switch opens, because of high exhaust temperature, the engine will stop and the exhaust and oil lamps will go out.
 
Oil Lamp Out. If the engine oil pressure falls below 12 psi, the oil pressure switch will open. The engine will stop and the oil lamp will go out.
