Troubleshooting
Before contacting the Humminbird Customer Service, 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,
• the fuse is operational, and
• the battery voltage of the power connector is at least 10 Volts.
Correct any known problems, including removing corrosion from the battery terminals
or wiring, or actually replacing the battery if necessary.
