Troubleshooting - Humminbird HELIX 5 SONAR Operation Manual

Troubleshooting

Before contacting 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.
Fishfinder Doesn't Power Up
If your Fishfinder doesn't power up, use the Installation Guide that also comes with it for specific
confirmation details, making sure that:
• the power cable is properly connected to the Fishfinder 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
• 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.
Fishfinder Defaults to Simulator with a Transducer Attached
A connected and functioning transducer will cause the newly-started Fishfinder to go into Normal
operating mode automatically. If, when you power up the Fishfinder, it goes into Simulator mode
automatically, even though a transducer is already connected, this means that the control head
is not detecting the transducer. Perform the following troubleshooting tasks:
• Using the Installation Guide that also comes with your Fishfinder, check to make sure that
the transducer cable is securely connected to the Fishfinder. Reconnect if necessary, and
power up the Fishfinder again to see if this fixes the problem.
• Replace the non-functioning transducer with a known good transducer if available and
power up the control head again.
• Check the transducer cable. Replace the transducer if the cable is damaged or corroded.
