What will you do if your depth sounder stops working as you reach a harbor with a bad reputation, or if your navigation stops working just before you set off for a day of fishing?
Reading the owner's handbook is the first step when trying to fix any piece of electronic equipment or system on your boat, and ideally, you should have done this before the problem arises. Having a basic understanding of how your boat's wiring system is installed and operates will make it easier to troubleshoot issues and pinpoint problems quickly. Most user manuals include a troubleshooting section to help guide you when something goes wrong.
If you're dealing with older boats or boats that have been rigged and wired extensively, you'll be thankful for having invested time in learning your boat's electrical system. Trust me—once that first glitch happens, and it will, you'll be glad you did.
No Power & What To Look At First
When a piece of electrical equipment won't turn on, the first thing to inspect is the power connection at the device for signs of corrosion or loose connections. If your boat's power panel includes a volt meter, check to see if it's displaying the correct voltage and ensure all fuses are intact.
For devices that work inconsistently or have lost some functionality, check the plugs and cable connections. Over time, these can corrode or become loose due to vibration. Unplugging and re-plugging cables can often solve the issue. Inline cable connections can also come loose, especially from wave vibrations, so inspect them carefully. Follow the wire in question and check for breaks or damage along the path.
New Boat Wiring Is Underwhelming
If an accessory powers on but the display is blank, start with the basics. Ensure the device is functioning properly, or check if it has defaulted to a low contrast mode or unusual factory setting caused by battery drainage while your boat was stored. “Operator-induced anomalies” are also possible, where other control elements may be at fault. For example, if your radar isn't detecting targets, verify that it's set to the correct range and that gain and sensitivity settings are properly configured.
The Obvious Is Not The Culprit
If you've checked all connections and the power issue persists, it's time to grab your multimeter and dig deeper. If you own a boat, this is your wake-up call to learn how to use one, as they can be lifesavers in troubleshooting electrical issues.
Having a multimeter on hand and knowing how to use it can make all the difference when dealing with electrical failures. By properly diagnosing the problem, you'll be able to resolve issues more efficiently and avoid unnecessary headaches on the water.
