PiranhaMAX Portable Case Maintenance
• If the portable case comes into contact with salt spray, wipe the affected
surfaces with a lint-free cloth, then apply a commercially available
anti-corrosive treatment to all exposed electrical contacts.
• If the portable case bag becomes dirty, clean the bag with mild soap, water,
and a soft rag or brush and then hang it up to dry.
How to Remove Water from the Portable Case
Open the front zipper and pull the case down to allow water to exit the case. If
needed, remove the case from the plastic base and air-dry it. Follow recommended
maintenance procedures for salt spray exposure, if needed.
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
Customer Service 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. If
the unit is wired through a fuse panel, ensure the panel is powered. Often
accessory fuse panels are controlled by a separate switch or the ignition switch.
Also, often a fuse can appear to be good when it is not. Check the fuse with a
tester or replace it with a fuse known to be good.
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.
