1. Nothing happens when I turn the unit on.
Check the power cable connection at both ends. Be sure the cable is connect-
ed correctly to a reliable power source—red lead to positive, black lead to neg-
ative or ground. Ensure the power available at the mount 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 in fact is not. Check the
fuse with a tester or replace it with a fuse known to be good.
Check the power connection to the Pro Craft unit. 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. Finally, ensure the unit is firmly seated on the
mount. The electrical contacts are not made until the unit is fully seated.
Ensure the metal cable retainer is properly installed in the mount. If not, the
power connected may push out when the unit is put on the mount.
2. There is no transducer detected.
The Pro Craft unit has the ability to detect and identify that a transducer is con-
nected. If, at power up, a message indicates “transducer not connected,” only
simulator operation is possible. First, ensure that an appropriate transducer con-
nector is positioned correctly in the connector holder, and that the unit is fully
seated on the mount. The Pro Craft unit will work with the standard dual-beam
transducer.
Second, inspect the transducer cable from end to end for breaks, kinks, or cuts
in the outer casing of the cable. Also ensure the transducer is fully submerged
in water. If the transducer is connected to the unit through a switch, temporar-
ily connect it directly to the unit and try again. If none of these items identifies
an obvious problem, the transducer itself is probably the problem. Be sure to in-
clude the transducer if returning the unit for repair.
3. There is no bottom reading visible on the display.
There are a number of possible causes for this condition. If the loss of bottom
information occurs only at high boat speeds, the transducer needs adjusting. If
