Why Does My Garmin Fish Finder Keep Turning Off?
Navigating the waters with a reliable fish finder is essential for many anglers and boaters. Garmin, a renowned name in marine electronics, offers a range of chartplotters and fish finders that are trusted by many.
However, like all electronic devices, there can be moments of unpredictability. One common issue some users face is their Garmin fish finder turning off intermittently.
If you’re grappling with this problem, you’re not alone. Let’s dive into the potential causes and solutions.
Garmin Chartplotter Powers Down Intermittently
When your Garmin marine device shuts down without warning, it can be both frustrating and concerning. Here are some troubleshooting steps to help you identify and possibly rectify the issue:
Power Cable Fuse Check
Before diving deep, start with the basics. Ensure that the power cable fuse is of the correct size and that its element remains intact. You can verify the fuse’s condition by using a multimeter. Connect it to both ends of the fuse and measure for resistance. A good fuse should display close to 0 ohms on the multimeter.
Voltage Verification
Garmin chartplotters need at least 12 volts to function optimally. Always refer to your device’s installation guide to know the acceptable voltage range. To test the voltage, focus on the female end of the device’s power cable – the part that connects directly to your Garmin device.
Power Cable Integrity
A damaged or modified power cable can be the culprit. Check for any signs of cutting, nicking, or unauthorized extensions, as these can lead to power inconsistencies.
Monitor Voltage Fluctuations
Voltage drops or spikes can cause sudden shutdowns. For instance, your device might turn off the moment you start the engine or when you increase the boat’s speed. To keep an eye on this, add a voltage data bar to your chartplotter. This will help you track any voltage changes in real-time.
Connection Point Examination
Over time, the ends of wires (both power and ground) can degrade. If the length permits, consider cutting off the old ends, stripping back the sheathing, and establishing a fresh connection.
Corrosion and Oxidation
These are silent killers for electronic connections. Ensure that both the power cable and the device power port are free from corrosion and oxidation. If you spot any, gently clean them using a microfiber cloth with mild soap and water. Steer clear of harsh chemicals, especially those containing ammonia.
Power Cable Contacts
If you frequently remove the power cable from the device, the bronze connections might undergo mushrooming or spreading.
Regularly inspect these contacts for any signs of wear or damage.
Fuse Panel or Wire Block Usage
Sometimes, the issue might lie with the fuse panel or wire block. As a troubleshooting step, try bypassing these components and wire your device directly to the battery.
If, after trying all the above steps, your Garmin fish finder still powers down intermittently, it’s time to seek professional help. Contact Garmin Support for further assistance.
