Repair Humminbird finder? - Kayak Fishing Adventures on Big Water’s Edge

I have been ready to trash my nearly new H-Bird many times because it has not powered up. It happened the last time I went out.

In every case the problem has been with the power source not the fish finder. H-birds, and probably most other fish finders are very sensitive to voltage. If you have the polarity reversed... no go. If you have a bad connection with the battery or somewhere in the wires going to the device... also no go.

Check the voltage at the battery, and at the plug that connects to the fish finder. If you have less than 12 volts with a fully charged battery, your problem is somewhere in the wires or the connectors.

You can pick up an inexpensive but useful Digital Volt Meter at Harbor Freight Tools for less than $5. This device is now part of my kit when heading to the launch.
