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.

Engine Starter Circuit

A common calamity for which we often get requests for a service call is the engine failing to start or even “turn over”.

Importance of Remote Battery Switches

A common conundrum with battery banks and their main disconnect switch is that batteries are often located in the engine room space. The cable to disconnect switch for the battery should be as short as possible and by commonly accepted standards, within 72” from the battery terminal post. The problem arises that in the situation of a catastrophic event, like a battery exploding, it should be possible to easily access and disconnect the battery without entering the space in which the battery is contained.

Engine Switches and Senders

Most boat operators are familiar with their gauge set and are aware that there is a device on the engine providing a signal to the gauge that allows it to provide useful information. However, many boaters are unfamiliar with the nature of those engine mounted devices.

Switch Terminology

In order to understand switches, it is necessary to understand the terminology associated with switches.First, a switch is a device that controls the flow of electricity by either stopping the flow (the switch is “off” or more correctly it is “open”), or by diverting the flow as with a changeover switch.

Reverse Polarity Shore Power

As a boater we love to travel. Boats enable us to travel. One of the many reasons we love being a boater. As we move from place to place we can sometimes come across situations we haven’t experienced before. The following is a guide of what to do when you find your boats reverse polarity lights come to light.

How to Keep Water on the Outside

Before taking your boat out on the water, it is important to check, check and check again. Some of our earlier blog articles talk about the importance of checking batteries. In addition to that, bilge pumps are undoubtedly one of the most important systems on any vessel and must be checked upon regularly. Many factors play a part on whether your bilge pumps will keep your boat afloat.

Protecting Your Boat From Galvanic Corrosion

Protecting your boat from various external elements is crucial in the long run. Our boats are made of many processed materials that want to return to their normal state by undergoing electrochemical processes - in other words, these materials want to corrode. Galvanic corrosion occurs when two dissimilar metals, for example copper and steel, are connected and submersed in an electrolyte (water) - this creates an electric charge.

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.

Keeping Clear

We all know storage space on boats is hard to find and easy to fill. When storing gear on boats we need to think about the items we are covering up.
