Why Hire a Certified Marine Professional

When dealing with straight service work (something just doesn’t work), we start by verifying the concern.  Next comes a visual inspection of the relevant equipment in that system (as much as possible,  sometimes access makes this not practical initially).  From that point we go into diagnosis to determine the problem.  Often this involves some basic existing electrical system tracing and labeling to determine what needs to be addressed, as well as makes the system more intuitive the next time someone needs to look at it.  After diagnosis comes the solution/repair.  If it is a failed part, before replacement, the question of “Why?” has to be answered.  Was it just time/had the component reached it’s service life? Was it the correct component for the desired application to start with?   Is it corrosion related?  Was it installed correctly (adequate wiring, location, ventilation, protection, etc.)?  The replacement of that component needs to address any issues as much as possible to prevent premature replacement or issues moving forward.  While this may seem like a drawn out process, it typically moves very quickly.

When installing new equipment, every effort is made to install that equipment in a manner consistent with the manufacturer's recommendation.  Beyond that, the same level of effort is made to meet either or both of ABYC and NMEA installation standards.  More times than not, (and frequently during service work) this involves removing abandoned equipment and/or wiring.  Sometimes, with new electronics installations, abandoned components and wiring can be found from multiple past installations.  This abandoned equipment has no business on the boat, and typically, beyond adding dead weight, is clogging and complicating wire runs and impairing visual inspection moving forward.  Electrical diagrams are almost always helpful when available and we are able to use programs like Autocad to create new diagrams for existing systems or upgrades if so desired.

Some additional questions to consider...

In the case of AC system power supply, this starts at the panel(s) fed from the shore power pedestal and/or generator. With DC power, this starts with the size (number of batteries and amp hours per bank) and technology feeding the main panel(s).  In both systems, ensuring adequate power supply and wire sizing is crucial to proper system(s) operation. Voltage drop considerations and properly sized circuit protection are also imperative for a safe, proper functioning, as well as compliant system.

This small step makes diagnosing problems and/or adding equipment later much easier.  Unfortunately, if it hasn’t been done in the past it needs to be done at least at some level (on the system being serviced or added to at a minimum) to ensure proper and safe operation of that system moving forward.

Diagrams allow not only for proper planning of the install was well as a road map in the building phase, they are a great reference for future work and/or troubleshooting. Sometimes a simple sketch is adequate, but formal wiring diagrams do add the ability to be more easily backed up and accessed later.  They can be extremely time (money) saving later in the vessel’s service life.

“Housecleaning” in this situation is in reference to the removal of the old equipment/wiring/infrastructure belonging to systems on board that are no longer in use, supported, or being replaced.  It basically has been abandoned in place by a prior individual.  Rigging tubes, tower legs, wire runs, and equipment mounting spaces can easily be come very confusing and overcrowded by old infrastructure. It adds unnecessary weight to the boat and make future and current work more difficult, sometimes even impossible

Proper training (for the installation and service of a system, i.e. electrical) and execution in light of that training are necessary parts of any system operating to it’s potential and design intent.  Any system that is improperly installed cannot be expected to perform as the manufacturer intended.  Further, warranty of products can be void if not installed correctly, resulting in an opportunity to purchase the equipment and installation a second time.
