Rated Fuel Limit - This term indicates the maximum allowable fuel position (longest injection pulse). This position will produce rated power for this engine configuration.Reference Voltage - The reference voltage is a regulated voltage and a steady voltage that is supplied by the ECM to a sensor. The reference voltage is used by the sensor to generate a signal voltage.Remote Shutdown - The ECM disables the fuel injection signal when the remote shutdown switch is closed. This causes the ECM to shut down the engine. However, the ECM remains active. The air shutoff solenoid is not activated when the remote shutdown switch is activated.Secondary Electronic Control Module (ECM) - The secondary ECM is required by the Marine Classification Society for compliance. This ECM is used as a backup for the primary ECM in case the primary ECM fails. The ECM monitors the engine for problems. The ECM will shut down the engine if any problems are detected.Secondary Engine Speed/Timing Sensor - This sensor provides a variable amplitude and PWM signal to the ECM. The ECM interprets this signal as the camshaft position and the engine speed.Sensor - The sensor is a device that is used to detect a change in pressure, temperature, or mechanical movement. The information that is detected is converted into an electrical signal.Short Circuit - A short circuit is a condition that has an electrical circuit that is inadvertently connected to an undesirable point. An example of a short circuit is a wire which rubs against the engine block and this rubbing eventually wears off the wire insulation. Electrical contact with the engine block is made and a short circuit results.Signal - The signal is a voltage or a waveform that is used in order to transmit information typically from a sensor to the ECM.Speed Burp - A speed burp is a sudden, brief, unwanted change in the engine rpm.Starting Aid Switch - This switch is used for injection of a starting aid in cold weather. An example of a starting aid is ether.Static Timing - Static timing is the basis for correct fuel timing and valve mechanism operation. Static timing is determined by the timing ring and the alignment of the rear gear group.Subsystem - A subsystem that is used in this application is a part of the electronic system that relates to a particular function. An example of a subsystem is the throttle subsystem.Supply Voltage - The supply voltage is a constant voltage that is supplied to a component in order to provide electrical power that is required for the component to operate. The power may be generated by the ECM or the power may be battery voltage that is supplied by the vehicle wiring.System Configuration Parameters - System configuration parameters are parameters that affect the power rating family or emissions.Terminating Resistor - This is used to terminate the J1939 CAN data link. Refer to the installation procedures.Throttle Position - The throttle position is the interpretation by the ECM of the signal
