WIRING GP-FRONT 4992441 - Caterpillar

Engine Oil Temperature - This gauge indicates the engine oil temperature after the oil has passed through the oil cooler. The oil cooler is thermostatically controlled.
Exhaust Temperature - This gauge indicates the exhaust temperature at the exhaust inlets to the turbochargers. The two exhaust temperatures may vary slightly.The exhaust temperatures at the exhaust inlets to the turbochargers provide a good indication of engine performance. For engines with dry exhaust manifolds, the temperatures are representative of the actual temperatures of the valves. Monitor this parameter frequently.
Severe damage to the engine can result if the exhaust temperature at the inlet to the turbocharger exceeds the extreme limit.
Fuel Level - This gauge indicates the fuel level in the fuel tank. Normally, the fuel level gauge will register the fuel level only when the switch is in the ON position.
Fuel Pressure - This gauge indicates fuel pressure to the fuel injection pump from the fuel filter. A decrease in fuel pressure usually indicates a dirty fuel filter or a plugged fuel filter. As the fuel filter becomes plugged, there will be a noticeable reduction in the engine performance.
Fuel Temperature - This gauge indicates the temperature of the fuel. A high fuel temperature can adversely affect performance. If the temperature of the fuel is too low, the fuel filter may begin to plug. See this Operation and Maintenance Manual, "Fuel and the Effect from Cold Weather" for more information.
Fuel Usage - This gauge indicates the rate of fuel usage.
Inlet Manifold Air Pressure - This gauge indicates the air pressure (turbocharger boost pressure) in the air inlet manifold after the aftercooler. The inlet manifold air pressure depends on the engine rating, the load, and the operating conditions. To establish the normal inlet manifold air pressure, compare the data from the gauge to the data from the engine commissioning and look for trends.
Inlet Manifold Air Temperature - This gauge indicates the inlet manifold air temperature after the aftercooler. As the inlet air increases in temperature the following conditions occur: expansion of the air, less oxygen in the cylinders and less power. If the temperature of the inlet air is too high during full speed and load operation, the engine may consume excessive fuel.
Service Hour Meter - This gauge indicates the total number of clock hours on the engine.
System Voltage - This gauge indicates the voltage of the electrical system.
Tachometer - This gauge indicates engine speed (rpm). When the throttle control lever is moved to the full throttle position without load, the engine is running at high idle. The engine is running at the full load rpm when the throttle control lever is at the full throttle position with maximum rated load.
To help prevent engine damage, never exceed the high idle rpm. Overspeeding can result in serious damage to the engine. The engine can be operated at high idle without damage, but should never be allowed to exceed high idle rpm.
Note: The high idle rpm and the full load rpm are stamped on the Information Plate.
