    Approximately, two years ago our old girl started showing signs of a cold. She started out with the occasional sniffles that slowly progressed over time from a random hiccup to more frequent engine surging. As the doctor, I knew that for an engine to run efficiently it needed three things in the proper proportions and at the right time, fuel, air and ignition. So the series of tests began.

    Troubleshooting marine ignition and starting problems will go much easier if you have a basic understanding of how all the components relate to each other and their specific duties. Overall, the system is similar to an automobile with a few exceptions. In a car, the frame serves as a pathway for the DC current to flow back to the battery or ground. Obviously, on a boat made of fiberglass this is impossible, even if the boat is made of metal this still ...

    OK so I gotta get this battery relocation project going. I hope to get batteries and supplies together this week. I've figured on going with eight golf cart batteries with as much capacity as I can afford and fit into my battery boxes. I like what I hear about Trojan batteries, they are priceyer though. I'm either going with eight Trojan 220 ah golf cart bateries, or for the same money I can get eight US Batteries rated at 245 ah. What would you do?

    I plan on running 2/0 cable from the batteries to the battery switch located in the settee above. ...

    With the demand to keep manufacturing costs low, many manufacturers of cruisers up to forty feet don't provide an adequate house battery system. For the average daytime boater, this normally does not present much of a problem, but when you begin to spend overnights on the hook the inadequacies quickly become apparent.

    Some boaters never experience this problem because they run their generators constantly. Of course, this adds to the expense of boating in both fuel burn and maintenance, ...

    The last few times you used your forward cabin lights you noticed they flickered and were not as bright as they should be. Today when you switched them on the circuit breaker popped. You reset it and it popped again! What now?

    Here is a word of caution before we begin. AC wires on boats use the following color convention, black = hot or current ...

    For many of us our first boat is not likely to be a brand new mega-yacht fresh off the showroom floor. More likely it will be a used boat that has experienced a few owners with each one adding their personal touch of electrical devices from trolling motors, depth sounders to extra batteries. One of the most intimidating aspects of boat repair for most people is tackling the marine electrical system. ...
