Troubleshooting

Before contacting the Humminbird® Customer Resource Center, please read the followingsection. Taking the time to reviewthese troubleshooting guidelinesmay allow you to solve a performanceproblem yourself, and therefore avoid sending your unit back for repair.

NOTE: Do not attempt to repair the HDR 650 yourself, as there are no user-serviceable parts inside, and special tools and techniques are required for reassembly in order to maintain the waterproofintegrity of the housing. Repairs should be performed only by authorized Humminbird® technicians.

HDR 650 Doesn't Power Up

If your HDR 650 doesn't power up, refer to the Installation section, and make sure that:

•the power cable is properly connected to the HDR 650;

•the power cable is wired correctly, with red to positive battery terminal and black to negative terminal or ground;

•the fuse is operational; a fuse can often appear to be good when in fact it is not; check the fuse with a tester or replace it with a known good fuse;

•if the unit is wired through a fuse panel, make sure that the panel is powered, as accessory fuse panels are often controlled by a separate switch, or even the ignition switch of the boat;

•the battery voltage of the power connector is between 10 and 20 VDC.

Correct any known problems, including removing corrosion from the battery terminals or wiring, or actually replacingthe battery if necessary.
