Yea, I know, you don’t have time for a lot of theory BS. I get that, we are all busy. But I can absolutely guarantee that you will have better results and happier cruising if you break a half hour or so free for this, and the next two chapters.
Can’t I just pay someone else to get my cruising boat electrical system up to cruising standard, you ask? I wish, but, sadly, it never ceases to amaze me how ignorant many, perhaps most, technicians around boatyards are about how electricity works. Yes, even those who have worked on boat electrical systems for years.
And the ignorance of said technicians pales into insignificance when compared to the pure unadulterated rubbish spouted by many people who sell marine electrical equipment.
And don’t even get me started on the level of BS that flies on the forums when things like batteries and charging are discussed—you could drown in the stuff.
The point being that we can waste a boatload of money and still end up with an inefficient, unreliable electrical system if we don’t have this basic knowledge.
The good news is that if we understand just a little bit of electrical theory we will immediately be able to detect the rich aroma of marine electrical BS before any harm is done. And the even better news is that this stuff is not that hard to grasp.
Let’s do it.
