Negative Battery Switching Troubles

We recently had to trouble shoot a problem on a boat that had negative battery switching instead of positive. In North America, everything is switched (and fused) on the positive side of the battery. In Europe, some boats have both positive and negative battery switching (i.e. Beneteau) however, we have never seen a negative only battery switching before.

Line Loss

As discussed in earlier articles, marine cables have many different characteristics than their counterpart in the construction industry. The cables used in a marine environment need...

The Importance of Using Marine Cables for Marine Applications

In our daily lives when we have a problem we solve it in the most efficient and cost effective way possible. When presented with more than one option to solve an electrical problem for a marine application we will instinctively choose the least expensive one not taking into account or ignoring the fact that this decision may alter and even endanger our boats.

Maintaining Your Deep Cycle Battery

Although batteries are not the most expensive part on our boats, they are essential to them in that they feed the cranking power to our engine as well as keep us illuminated at night when the generator is not running. Batteries that feed the 12 - 24 volt circuit are at the heart of a boat and with a little tender loving care they will provide us with years of good service.

Fuel Sensors: A How-to Guide

Installing a fuel sensor or fuel monitoring system on your boat is not just another project to be left on the back burner. There are many benefits to having one on board, not just for your boat, but also for the environment. So how exactly do fuel sensors work? What are the benefits of having one?

Check and Check Again

There are always things that need to be maintained and checked on a boat - it is never a good idea to tuck your boat into its berth and forget about it. Many systems onboard need to be checked at least once a month, if not more. Pumps are a prime example of components onboard that should be used (meaning turned on or rotated) regularly to prevent them from seizing or letting the impellers dry out.

Quick Tips To Ensure Your Boat's Batteries Are Healthy and Ready for the Summer

Summer is coming and the marinas are coming to life again. Many of our boats have sat through winter without being turned on, and some of you are finding that all is well, while some are finding that things aren't quite the way you left them. I want to talk about battery conditions and what should be checked and/or monitored all year round.

How Simple DIY Battery Connection Checks Can Help Your Boat

Are your battery connections the best they can be? Here are some simple do-it-yourself checks that you can perform to help maintain the connections to the heart of your boat. These are simple checks and tasks that take no more than 10 minutes and will lead to peace of mind when you are at sea.

Little Mistakes, Big Problems

Sometimes the quality of a manufacturer's vessel is only as good as its workers. Let us look at some mistakes that must be corrected as soon as possible so that your boating experience is not disturbed by unnecessary problems.

Doing things the wrong way: equalizers and converters

There are many advantages to having a 24 volt system on your boat when adding high load DC powered devices like windlasses and bow thrusters. However, there are a few drawbacks to 24 volt battery systems - one of these drawbacks being that a lot of devices can only run on 12 volts.
