-
Fuse Rating Selection
The wiring diagram specifies the precise amperage rating for each fuse within the system. Using a fuse with a lower rating than specified can lead to premature blowing under normal operating conditions, while a higher rating fails to provide adequate protection against overcurrent. Selecting the correct fuse rating, based on the diagram’s specifications, ensures proper circuit protection and prevents damage to connected components. For example, using a 5A fuse where a 10A fuse is specified can cause the fuse to blow even under normal operating loads, leading to system interruption. Conversely, a 20A fuse where a 10A fuse is required might not blow quickly enough during a surge, potentially damaging the connected electronics.
-
Fuse Type and Placement
The diagram also dictates the type of fuse (e.g., blade, ATO/ATC) and its precise location within the wiring harness. This information ensures compatibility with the fuse holders and proper circuit protection. Using an incorrect fuse type or placing it in the wrong location can compromise the system’s safety and functionality. For instance, using a blade fuse in a system designed for ATO/ATC fuses can create a loose connection, potentially leading to overheating or arcing. Similarly, placing a fuse in the wrong location might leave a critical component unprotected.
-
Identifying Fuse-Related Issues
The wiring diagram aids in troubleshooting fuse-related problems. If a fuse blows repeatedly, the diagram helps pinpoint potential causes, such as a short circuit or overloaded circuit. This allows for targeted troubleshooting and prevents further damage to the system. Simply replacing a blown fuse without addressing the underlying issue can lead to recurring problems and potentially more significant damage. The diagram allows for systematic identification of the faulty component or wiring segment.
-
Preventing Damage from Overcurrent
Fuses protect the Lowrance ActiveTarget system by interrupting the flow of current in an overcurrent situation. This prevents damage to sensitive electronic components, wiring, and even the power source itself. An overcurrent situation can arise from various factors, including short circuits, faulty components, or excessive load. Without proper fuse protection, these events can lead to irreparable damage or even fire hazards. The fuses act as a sacrificial element, breaking the circuit before excessive current can cause harm to more valuable components.
Correct fuse implementation, as specified in the Lowrance ActiveTarget wiring diagram, safeguards the system from electrical damage, ensuring reliable operation and longevity. Understanding the diagram’s fuse specifications and their role in circuit protection is essential for preventing costly repairs and maximizing system performance.

5. Grounding Requirements
Proper grounding is crucial for the optimal performance and safety of a Lowrance ActiveTarget sonar system. The wiring diagram details specific grounding requirements to minimize electrical interference, ensure consistent operation, and protect sensitive electronics. Ignoring these requirements can lead to compromised sonar images, system instability, and potential damage to components.
-
Eliminating Electrical Noise
A solid ground connection provides a low-impedance path for stray electrical currents, minimizing noise and interference that can degrade sonar image quality. Without proper grounding, electrical noise from the boat’s engine, other electronics, or even atmospheric conditions can manifest as static, lines, or other distortions on the sonar display, hindering accurate interpretation of the underwater environment. A clean ground connection minimizes these disruptions, ensuring a clear and accurate sonar image. For example, a poorly grounded system might display erratic lines or “snow” on the screen, obscuring fish echoes and bottom structure.
-
Protecting Against Voltage Fluctuations
Grounding protects the system from potentially damaging voltage fluctuations. Surges or spikes in voltage, often caused by electrical faults or lightning strikes, can damage sensitive electronic components. A robust ground connection provides a pathway for these surges to dissipate harmlessly, preventing damage to the sonar unit, display, and other connected devices. This protective measure ensures the longevity of the system and prevents costly repairs. For example, a voltage spike without proper grounding could damage the sonar unit’s internal circuitry, requiring replacement or extensive repairs.
-
Ensuring Consistent System Performance
Consistent system performance relies on a stable electrical environment. Proper grounding contributes to this stability by providing a common electrical reference point for all components. This stabilizes voltage levels and minimizes potential differences that can lead to erratic operation or system malfunctions. A well-grounded system operates predictably and reliably, providing consistent sonar performance. Inconsistent grounding can lead to intermittent issues, such as the sonar unit randomly restarting or the display flickering, hindering reliable operation.
-
Adhering to Safety Regulations
Adherence to proper grounding procedures is often mandated by safety regulations for marine electronics. These regulations ensure the safety of the vessel and its occupants by minimizing the risk of electrical hazards, such as fire or electrocution.

Conversely, sonar data from the ActiveTarget system can be overlaid on the chartplotter’s map, providing a richer understanding of the underwater terrain in relation to navigational markers.
Network connections within the ActiveTarget system typically utilize Ethernet cables and NMEA 2000 protocols. The wiring diagram specifies the appropriate cable types, connectors, and network configuration settings required for successful integration. Incorrect wiring or configuration can lead to communication errors, preventing data sharing and potentially disrupting the functionality of connected devices. For example, using an incorrect cable type for the network connection can result in a failure to establish communication between the ActiveTarget system and other network devices. Similarly, incorrect termination of the NMEA 2000 network can lead to data corruption or complete network failure.
Understanding the network connection details within the wiring diagram is essential for maximizing the system’s potential. Correct implementation facilitates seamless data transfer between devices, enhancing situational awareness and improving decision-making on the water. Failure to adhere to these guidelines can limit the system’s functionality and prevent access to valuable integrated features. This understanding, therefore, is crucial for realizing the full potential of the Lowrance ActiveTarget system within a networked marine electronics environment.
7. Black Box Connections
The Lowrance ActiveTarget system often incorporates a “black box” module that serves as a central processing unit for the sonar system. This module manages data acquisition from the transducer, processes the sonar signals, and transmits the processed data to the display unit. The black box connections, as detailed within the wiring diagram, are critical for the proper flow of information and power throughout the system. These connections facilitate communication between the transducer, the black box, and the display unit, enabling the system to generate accurate and detailed sonar imagery. A failure in any of these connections can result in a loss of sonar functionality, hindering the ability to locate fish and interpret underwater structures. For example, a loose or damaged power connection to the black box can prevent the entire system from operating, while a faulty data connection between the black box and the transducer can result in a loss of sonar signal, rendering the system useless. Therefore, understanding the precise connection points and cable requirements, as outlined in the wiring diagram, is paramount for ensuring proper system functionality.
The wiring diagram specifies the correct cable types, connectors, and port assignments for the black box connections.
