Marine electrical systems can be scary, mysterious stuff. In this video series, we asked Professor Don Eley to show us what we need to know to untangle our own boat wiring. We’re continuing this series here in Part 2 with a look at marine battery cables, since they get the power from the source to where it needs to go.

Learn about choosing the right marine battery cables, connecting terminal ends, crimping & sealing. Getting this part right could be the difference between a system that lasts a lifetime or a big headache a few years down the road.

    As others has stated, it would be great to have a video or some commentary about galvanic corrosion and the ground circuit on boats. That topic is relevant to those of us with aluminum fishing boats with an ever increasing number of electrical doodads on them..

    Mr. Eley, Thanks for these informative videos.

    One topic I’d like to see covered is grounding systems for boats, particularly in relation to shore power connections.

    do you know that there is heat shrink that , has epoxy seal , so when you heat it the epoxy seals real good.

    Great series as always. Two things I would add to the wire crimp dialog. First, I put Oxguard on the wire before crimping it. Oxguard is used in home wiring whenever aluminum wire is fitted into a lug connection. It is a conductive paste. Second, I always use shrink tubing with a heat activated glue liner. That seals the wire to lug connection better than just plain heat shrink tubing.

    Fantastic start. Give us more. For the first time I’ve got an understanding of a crimped connection.

      It’s about 4th in our editing cue… January-ish. We can’t wait either.

    Excellent presentation in that it covers just enough but does not inundate you with tech science

    This looks like the start of a great series – keep them coming quickly! Don makes it very easy to follow.
