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.
