TROUBLESHOOTING
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 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 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 160. It is possible to force the power
cable connector into the collector plug 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.
Ensure the cables are properly installed into the collector plug and the
collector plug is properly seated into the 160.
2. The Unit Starts up in simulator mode.
The 160 has the ability to detect that a transducer is connected. If, at power up,
a transducer is not connected, the unit starts up in simulator mode.
Ensure that an appropriate transducer connector is used and the connector
is positioned correctly in the collector plug. Also be sure that the collector
plug is fully seated into the unit. 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, temporarily 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 include the
transducer if returning the unit for repair.
To manually override the simulator, select the Simulator C
turn to off. See C
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
