What size fuse to use when connecting a Humminbird 596c HD DI to the battery? Best regards John

If its too old to repair (humminbird is really great and well known for their repair shop!!). Time to invest in a NEW model. You will be GLAD you did.

I would use slip rings to tie existing cable to prop motor support shaft and mount transducer to motor housing. 'slip ring'--metal ring a little bigger than shaft with a nipple the size of the cable. OR call the bird at 1-800-633-1468 or www.humminbird.com/Category/Company/Contact-Us/ and use some southern/country slang when talking. Best of luck 'you all'.

May require a software update.
register your unit at OnixSeries (this is a link to humminbird)
On your "My humminbird" page you will find free software updates for your particular unit.
download the latest update to an SD card and follow the instructions for the installation process.

Best precaution is an in-line fuse of a Slow Blow 5 amp near the battery or power distribution terminal.

Hi, check the power and earth connections to the unit. Also it will have a fuse on the positive wire, if it is a glass type fuse get rid of it and fit a blade fuse and holder. Hope this helps, regards Phil.

Hi!
If the unit shuts off on its own, firstly check your power supply. I keep seeing customers running their ssounders from a small, portable battery configuration that doesn't put out the correct voltage...mostly seen with AA size batteries being rated at 1.2 or 1.3 volts (8 batteries times 1.2 volts is only 9.6 volts).
If the power supply is not the issue then I would say the internal power circuit is suspect...this can only be repaired by a competent repair person who knows how and what they are doing. If you open the unit up, you'll not only void the warranty, you run the risk of killing the entire unit from static shock.
Best of luck in your repair!

Hi!
Here is the manual on how to configure hand held gps units to Humminbird sounders:

Hi,

Most probable component that has gone bad and capable of blowing the 5V fuse would be:

• voltage regulator IV or transistor;
• reverse protection diode;
• zener diode;
• shorted capacitor.

As the 5VDC normally supplies the logic circuitry, perhaps diagnosis and tests should be focused within that area.

Hope that this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
