There is no fuse box, they use inline fuses. Chase the wiring back to the battery, somewhere near the battery or the radio/fish finder will be a fuse on the power wire.

Contact Hummingbird in Eufaula, Ala. #800-633-1468. Good luck.

Battery too low
Fuse blown
Corroded connections at battery, fuse, connector

Good Fishin!

It should work right out of the box. It may have trouble picking up satellites, especially if you are testing it inside your house. A lower-end unit like this isn't going to have as powerful an antenna as more expensive models, so be sure you are outside, with a clear path to outer space and it should work!

Hope this helps.
