Troubleshooting

Do not attempt to repair the PiranhaMAX™ yourself. There are no user-serviceable

parts inside, and special tools and techniques are required for assembly to ensure

the waterproof integrity of the housing. Repairs should be performed only by

authorized Humminbird® technicians.

Many requests for repair received by Humminbird® involve units that do not

actually need repair. These units are returned “no problem found.” If you have a

problem with your PiranhaMAX™, use the following troubleshooting guide before

calling the Customer Resource Center or sending your unit in for repair.

1. Nothing happens when I turn the unit on.

Check the power cable connection at both ends. Be sure the cable is connected

correctly to a reliable power source — red lead to positive, black lead to

negative or ground. Ensure the power available is between 10 and 20 VDC.

Check the power connection to the PiranhaMAX™. It is possible to force the

power cable connector into the cable holder incorrectly. If the connector is

reversed, the unit will not work. Examine the contacts on the back of the unit

to ensure there is no corrosion.

2. There is no transducer detected.

The PiranhaMAX™ has the ability to detect and identify that a transducer is

connected. When powering on, if a message indicates “transducer not

connected”, make sure that an appropriate transducer connector is plugged

into the unit. In addition, inspect the transducer cable from end toend forbreaks,

kinks, or cuts in the outer casing of thecable.Also make sure that the transducer

is fully submerged in water. If the transducer is connected to the unit through

a switch, temporarilyconnect it directly tothe unitand try again.If noneof these

actions identifies an obvious problem, the transducer itself is probably at fault.

Be sure to include the transducer if returning the unit for repair.
