sage CONNECTED appears. If a series of dashed lines is shown, no transduc-
er is connected or there is a problem with the transducer or cable.
If you are using multiple transducers, switch between transducers to confirm
the connections for each.
Boat Speed/Water Temperature Connection.
Other connections tested
include the boat speed and surface water temperature sensors. These
accessory sensors can be purchased independently or together as a single
sensor (see the Humminbird Accessories catalog). If the sensors are con-
nected and working properly, a “connected” message appears.
The speed input feature only works when the boat is in motion as the pad-
dle wheel on the speed sensor must rotate to be detected.
Voltage Input.
Another connection tested is the voltage input, and is
especially helpful in diagnosing input voltage problems. The current input
voltage is displayed. If voltage fluctuations or power supply in excess of 20
VDC or less than 10 VDC is suspected, use the diagnostic screen to confirm
input voltage. Often, small outboard motors do not effectively regulate
voltage when operated at high engine speeds.
Use Diagnostic while running the boat at high speeds to show the voltage
gain. Also, if you are using the Tracker unit in portable configuration or
from the trolling motor battery, Diagnostic can be used to evaluate the
health of the battery by showing the current voltage.
Total Time.
The total time category indicates the total time the unit has
been in use since shipped from the factory. It is normal for some hours to
appear in the total time when the unit is new due to factory testing. While
this is often of interest to the user, it is primarily a diagnostic tool for the
repair technician should the unit need service.
MAINTENANCE
Your Tracker unit is designed to provide years of trouble free operation with
virtually no maintenance. Follow these simple procedures to ensure your
Tracker unit continues to deliver top performance.
