FLOW CHART
Check all J-Box
and Load Cell
cables for cuts
or pinched/flat
spots.
START
YES
NO
Does the indicator come on?
Is the reading on the Indicator
stable?
YES
Put your weight on each load
cell. Does the indicator
respond to your weight?
NO
If your display is unstable, or flashes
“±RANGE” disconnect the j-box cord
from Indicator. Is display still unstable?
NO
YES
YES
Your Indicator is probably
defective. Try another Indicator
to verify.
Note:
Be aware of
electrical interference that might
affect Indicator, such as mobile
phones, CB radios, radio
towers, electrical motors, etc.
Make sure Load Cell cables are
not attached to hydraulic lines or
reservoir.
Are the readings all
positive? If not Load Cell is
upside down.
Poor Connection
: Take them apart and
clean connections. (Rust or paint should be
wire brushed.) Then reconnect and tighten
securely.
Bad Battery:
Replace battery (weak battery
may test good if tested with no load on
battery)
Bad Power Cord:
Make sure red wire is
connected to (+) positive side and black wire
is connected to (-) negative side. When using
a multimeter to check for voltage, measure
between pin 1 (pos) and pin 2 (neg). Meter
should read between 10.5 and 14.5 volts DC
if using a tractor power cord, black wire is
positive and white wire is negative.
Does the scale weigh you
approx. the same over all Load
Cells? (Weight will not be
accurate)
YES
NO
Remove the cover from your J-Box
Is there moisture inside
the box?
YES
Dry out your J-Box (use a hairdryer).
Check cable strain reliefs for
tightness. Cables have drip loops. Is
lid gasket damaged?
NO
Look for loose
connections. Watch your
Indicator display while
moving the wires and
pressing on the circuit
board inside the J-Box.
You will see if there is a
loose connection or bad
solder joint.
Your Indicator is probably not set-up and
calibrated correctly. Check the decal on
the bottom of Indicator. It shows what type
of Load Cells the Indicator was calibrated
to. By pressing the on key while the
Indicator is already on, you will get the
Indicator’s “Set-up” and “Cal” numbers.
See if they compare to the set-up and
calibration numbers on the Indicator.
Contact Dealer for further information.
Fix or replace the
J-Box
Did the J-Box have
a bad connection or
loose wire?
YES
NO
