Troubleshooting - Humminbird HELIX 5 SERIES 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.
HELIX Series Doesn't Power Up
If your control head 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 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.
HELIX Series Defaults to Simulator with a Transducer Attached
A connected and functioning transducer will cause the newly-started control head to go into
Normal operating mode automatically. If, when you power up the control head, 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 control head. Reconnect if
necessary, and power up the control head 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.
