Information:

AC Voltmeter
AC voltmeter (2) shows the potential difference (voltage) between phases T1/U and T2/V.Oil Pressure Gauge
Oil pressure gauge (17) shows engine lubrication pressure in both kPa and psi.
Simplified schematic
(17) Oil pressure gauge.As soon as the engine starts and switch ESS (CT) closes, oil pressure gauge (17) is connected across battery voltage. There is a relation between the current flow in this circuit and the engine oil pressure read on the gauge. The oil pressure sending unit controls the current flow by a change in resistance according to the change in engine oil pressure.Water Temperature Gauge
Water temperature gauge (18) shows the engine coolant temperature in both centigrade (°C) and Fahrenheit (°F).
Simplified schematic
(18) Water temperture gauge.As soon as the engine starts and switch ESS (CT) closes, water temperature gauge (18) is connected rcross battery voltage. There is a relation between the current flow in this circuit and the coolant temperature read on the gauge. The water temperature sending unit controls the current flow by a change in resistance according to the change in coolant temperature.Engine Control Switch
The engine control switch can be turned to four positions:STOP position - When turned to this position from the manual position, contact 11 (line 56) opens. When contact 11 is open the run relay (line 56) is deenergized and shuts down the engine. The ECS also opens contact 7 (line 36) and closes contact 8 (line 37). This will maintain battery (B+) to fault relays and fault lights that may have energized under a fault condition. The engine control switch should be kept in the STOP position while a fault is being corrected.When the ECS is turned to the STOP position from the AUTO position, contact 10 (line 57) opens. When contact 10 is open, the run relay (line 56) is deenergized and shuts down the engine. The ECS also opens contact 6 (line 36) and closes contact 8 (line 37). This will maintain battery (B+) to fault relays and fault lights that may have energized under a fault condition. The engine control switch should be kept in the STOP position while a fault is being corrected.OFF/RESET position - If a fault occurs, the engine will automatically shut down and light the correct fault light. The ECS is turned to the STOP position. After the fault is corrected, the ECS is turned to the OFF/RESET position to reset the fault relay and turn off the fault light. Power is still available to panel illumination lights (line 10) and the fault lamp test circuit. This position can also be used for normal shutdown of the engine.AUTO position - For standby application, the ECS is turned to the AUTO position. In this position, the engine starts when remote initiating contact (line 58) closes.MANUAL position - This position starts the engine. If a fault should occur, the panel will automatically shut the engine down and indicate the fault.Four Light Fault Board
There are four fault indicator lights and relays mounted on a printed circuit board assembly. If the
