TROUBLE SHOOTING CHART
Symptom Possible Cause
Unit is turned on, but no
display and motor is not
running. Check for bad connections, proper hook
up polarity, and make sure you have a
good, fully charged, battery.
Unit is turned on and
the motor is running,
but there is no display. Supply voltage too low. The unit will
show no display if the voltage is below
10 volts. Check while unit is running.
Unit runs well for a
short time, then lights
fade out or unit quits. Low battery or bad connection. Voltage
may be good when checked, but will fall
as unit runs.
Unit runs and shows
display light, but does
not read depth. Transducer is not plugged in, not in con-
tact with the water. Unit needs to be set
to a deeper range or higher gain.
Unit works, but needs
high gain to see bottom
or targets. Transducer is not aimed correctly or
needs to be cleaned. In-hull mount may
be loose. Remove S-Cable
Unit works, but has too
many lines on the dis-
play. Can't tell what is
what. Improper transducer mounting. Also,
gain may be set too high or ,if gain is set
to minimum, you may need an S-Cable
(see page 23).
Unit works well when sit-
ting still or when slow
trolling, but loses reading
at higher speeds. Improper transducer style, installation,
or adjustment causing a loss of smooth
water flow under the transducer when
the boat reaches a certain speed.
Unit shows noise when
engine or electric motor
is turned on. Defective engine or electric motor. Also
can be improper wiring or missing
ground in electrical system.
Everything is working
great, but cannot catch
any fish. That is why they call it “fishing” and not
“catching”. We here at Vexilar experience
this often. --- Just have fun.
