Troubleshooting
Before contacting the Humminbird Technical Support, please read the following
section. Taking the time to review these troubleshooting guidelines may allow you
to solve a performance problem yourself, and therefore avoid sending your unit back
for repair.
Fishing System Doesn't Power Up
If your Fishing System doesn't power up, use the installation guide that is included
with your Fishing System to confirm specific details, making sure that:
• the power cable is properly connected to the Fishing System control head,
• the power cable is wired correctly, with red to positive battery terminal and
black to negative terminal or ground, and the drain/shield wire to the boat's
chassis ground terminal,
• the fuse is operational, and
• the battery voltage of the power connector is at least 12 Volts.
Correct any known problems, including removing corrosion from the battery
terminals or wiring, or actually replacing the battery if necessary.
