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.
Fishing System Defaults to Simulator with a Transducer Attached
A connected and functioning transducer will cause the newly-started Fishing System to go into Normal operating mode
automatically. If, when you power up the Fishing System, 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:
∆ Check the connections of all transducers that are connected to the control head or Ethernet network. See the transducer
installation guide that was included with your Fishing System for connection information. Reconnect if necessary, and power
up the Fishing System 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.
