How to test a galvanic isolator that doesn't have a monitoring system
Posted by Liam Kennedy on 1/21/2019 to
Corrosion
Galvanic isolators are a bit difficult to test. Current ABYC standards require that galvanic isolators be self testing. For testing older isolators without this feature there are a number of methods that can be used, the one that follows is one that I found most useful.
What is a galvanic isolator and why should my shore power system have one?
Posted by Liam Kennedy on 1/21/2019 to
Corrosion
A galvanic isolator is a device used to block low voltage DC currents coming on board your boat on the shore power ground wire. These currents could cause corrosion to your underwater metals; through hulls, propeller, shaft etc.
Installing a High Power marine alternator on your boat.

Alternators
Arguably, there is no more worthwhile electrical project you can undertake on your boat to improve comfort and convenience than the installation of a high power alternator. Having a high power alternator will provide you with a substantial improvement in the availability of electrical power on board.
Why is my Amp Hour Meter giving strange readings after its winter break?
Posted by Liam Kennedy on 1/21/2019 to
Battery Monitoring
Amp hour meters do a great job at assisting the boat owner with battery management. They provide an accurate reading of voltage and of amps going in and out of the batteries and by keeping track of these readings over time they can provide a reading of "amp hours" or the state of charge of the battery as a percentage. They also often maintain a record of historical data and can use that to figure out battery efficiency.
How big a battery bank do I need?
Posted by Liam Kennedy on 1/18/2019 to
Batteries (Conventional)
For most people to answer to this is "as big as possible". Charlie Wing's book the "Boatowners Illustrated handbook of Wiring" has a very good explanation of how to calculate the capacity you need. The calculations start by working out what your daily load will be both at anchor and while underway.
Should I hook up batteries in Parallel or keep them in separate banks?
Posted by Liam Kennedy on 1/18/2019 to
Batteries (Conventional)
There may be some disadvantages to hooking up batteries in parallel but there are also considerable advantages. The main disadvantage as I see it is that as the batteries get old one will fail first, quite often by getting a shorted cell.
How do I charge two battery banks on my boat and still keep them separate?
Posted by Liam Kennedy on 1/18/2019 to
Batteries (Conventional)
The simplest way, if you can remember to do it, is to turn your battery switch to "BOTH" when charging, and turn it back to 1 or 2 when you are finished. This solution is unsatisfactory for those who sometimes forget and then end up with a flat battery from time to time.

An overview of wiring standards for boats in the US
Posted by Peter Kennedy on 11/16/2018 to
Electrical Standards
he standards that apply to wiring your boat in the US are the ABYC standards and the Code of Federal Regulations Title 33 CFR Sections 183.401 - 183.460 The ABYC standards are voluntary and the CFR standards are mandatory. The ABYC standards incorporate the CFR standards so a boat built to the ABYC Standards should automatically meet the CFR standards. This article is a brief introduction to the subject
