ELECTRONICS TROUBLESHOOTING AND REPAIR

When Your Electronics Fail, Getting Back on the Water Matters

Your boat's electronics are among the most important systems onboard. Modern vessels rely on chartplotters, GPS, depth sounders, radar, AIS, VHF radios, autopilots, electronic compasses, wind instruments, engine displays, and networked MFDs to help the captain navigate safely and make informed decisions. Channel markers, shoals, shipping channels, weather information, safe harbors, depth information, and vessel traffic can all depend on properly functioning marine electronics.

Some failures are primarily an inconvenience. An autopilot that stops working, for example, may make a long trip much more difficult. Other failures can have a much greater impact. Losing navigation, depth, radar, AIS, or communications equipment can cause an owner to postpone a trip or decide that the boat shouldn't be used until the problem is resolved.

Fast, Accurate Marine Electronics Troubleshooting

When electronics fail, replacing the equipment isn't always the answer. The problem could be the equipment itself, its power supply, wiring, network, antenna, sensor, configuration, or communication with another system.

Maritec Marine approaches marine electronics troubleshooting systematically by identifying the symptoms, isolating the affected system, testing the possible causes, and determining the actual source of the failure before recommending a repair or replacement.

We troubleshoot problems involving:

Marine electronics power and wiring
NMEA 2000 and marine network communication
Multifunction displays and chartplotters
GPS and heading sensors
Radar systems
Sonar and transducers
Autopilots
VHF and AIS
Wind instruments and sensors
Engine gauges and engine-data displays
Digital switching systems
Battery and charging systems supporting electronics
Antennas and RF-related equipment
Bow thrusters and windlasses
Remote monitoring and connected systems

Network Problems Can Look Like Equipment Failures

One of the most common challenges with modern marine electronics is determining whether the problem is actually inside the equipment.

A display that isn't receiving GPS information may have a perfectly good GPS antenna. A depth display that suddenly stops showing depth may have a working MFD but a network, power, transducer, or communication problem. An autopilot that isn't responding may have an issue with its network, heading sensor, rudder feedback, drive, or configuration.

NMEA 2000 network problems, poor connections, incorrect termination, insufficient network power, damaged cables, voltage drops, and communication problems between devices can create symptoms that appear to be equipment failures.

Our technicians understand how these systems are interconnected and can test the network and individual components to determine where communication is being lost.

Power Problems Are Often the Real Problem

Marine electronics are particularly sensitive to electrical problems. Low voltage, voltage fluctuations, voltage drop, poor connections, inadequate wiring, corrosion, and charging-system problems can cause electronics to shut down, reboot, freeze, or behave unpredictably.

Before replacing an expensive MFD, radar, autopilot, or other piece of equipment, it is important to verify that it is receiving the correct power under actual operating conditions.

A system that works perfectly at the dock may behave differently when multiple loads are operating, the engines are running, or the batteries are under charge or discharge. Proper troubleshooting means testing the system under the conditions in which the failure occurs.

Testing Sensors, Antennas & Connected Equipment

Marine electronics depend on information from sensors and external devices. When something isn't working correctly, we may need to test GPS antennas, radar scanners, transducers, wind sensors, heading sensors, rudder feedback units, engine interfaces, and other connected equipment.

Identifying whether the problem originates with the sensor, wiring, network, power supply, configuration, or display can prevent unnecessary replacement of expensive equipment.

Repair, Replacement or Warranty?

Sometimes the correct solution is a repair. Sometimes a component has failed and needs to be replaced. And sometimes an older piece of equipment has reached the end of its useful life and upgrading the system makes more sense than continuing to repair it.

As a marine electronics equipment reseller and service provider for many leading manufacturers, Maritec Marine can help customers determine the most practical solution.

When equipment is covered by a manufacturer's warranty, our relationships with manufacturers and suppliers can also help with warranty claims, replacement equipment, and manufacturer support.

Experienced Marine Electronics Troubleshooting

Marine electronics systems have become increasingly sophisticated, with multiple manufacturers and technologies communicating across the same vessel. Diagnosing these systems requires more than simply swapping components until something works.

Maritec Marine combines marine electrical expertise, NMEA networking knowledge, manufacturer training and certifications, and hands-on troubleshooting experience to identify the cause of difficult electronics problems.

Whether your radar isn't working, your chartplotter has lost GPS, your autopilot won't engage, your transducer isn't providing depth, your MFDs aren't communicating, your VHF or AIS has stopped working, or your electronics are repeatedly shutting down, we can help identify the problem and determine the best path to getting your vessel's systems working reliably again.
