Author Topic:   Eagle Fish Finder Problem

When I bought my bought about a month ago, the fish finder wasn't working. Then I took it out about a week later and it worked great. Now it's not working again. Does anyone else have the intermittent problem? Could it be caused by moisture? Rain? Washing the boat and getting it wet?

When I try to turn it on now, it beeps, and a vertical lines appears and then it dies. After that, pushing the on button gets no response for about 30 minutes, then it's the same thing.

Some Eagles are sensitive to battery voltage, eportfolio. Too low or too high and they wont work.

Another possibility is a poor (intermittent) power connection.

eportfolio, I agree with JB, it's probably your power connection. I had the same problem, even had the manufacturer replace the back with a new DC connection. It worked for awhile and the two small pins broke off again. Fed up, I pulled the back off the sounder and run the power wires out and made a permanent connection. I never had another problem - other than I had to leave the sounder in the boat all the time.

Well, I just recharged my battery to full power and the fishfinder still doesn't work.

When I hit the ON button, I get a quick vertical black line on the monitor and a beep, then it goes blank and silent. After that, I can't get any response for at least 20 minutes or more. When I try again, I get the same thing.

Can anyone expand on what to do to check the power connection? Is it worth repairing or just look to buy another?

Any suggestions?

did you try calling the Eagle tech support. Since they and Lowrance are the same company, I would think that they would assist with the problem. With all the Lowrance/ eagle research i did, I have only read Great things about the customer support/ tech line.

How to check a power connection:

Obtain a reliable voltmeter. Connect the voltmeter to the source of power. Measure the voltage. Compare the measured voltage with the voltage required by the device.

Follow JimH's advice. Buy or borrow a decent volt meter. Even a $5 one from Harbor Freight will tell you what you need to know. You need to compare the voltage you have available at the battery to the voltage you are seeing at the device having problems. Thirty years of being around boats would lead me to the possibility of having a corroded connection somewhere in your wiring between the battery and the unit. Also check the amount of corrosion visible in the power connector. The power lead for my eagle fish finder and my GPS chart plotter tend to grow corrosion in the connector over time (since I don't have them connected to a switch and I perform low level electrolysis between the pins when water bridges the two pins)

That being said, I have purchased used boats with defective electronics and tossed said defective electronic device into the trash can. You may choose to upgrade if you were not very impressed the day it did work.
