Troubleshooting
Before contacting the Humminbird® Customer Resource Center, 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.
1100 Series™ Doesn’t Power Up
If your 1100 Series™ doesn’t power up, use the Installation section of this manual for specific
confirmation details, making sure that:
• the power cable is properly connected to the 1100 Series™ 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.
1100 Series™ Defaults to Simulator with a Transducer Attached
A connected and functioning transducer will cause the newly-started 1100 Series™ to go into
Normal operating mode automatically. If, when you power up the 1100 Series™, 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 section of this manual, check to make sure that the transducer
cable is securely connected to the 1100 Series. Reconnect if necessary, and power up
the 1100 Series™ 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.
