3. Check the load cell and cable connectors to be
sure they are free of dirt, grease, and moisture.
4. Plug the cables into the load cells and tighten the
connectors until resistance is felt. Tighten the
connectors an additional 1/4 turn using only your
fingers; pliers are not necessary. The additional
tightening will seat the weather-proofing O-ring
that is inside the cable connectors.
5. Route the truck (channel 1) cable from the
transmitter to the indicator. Wherever the cable
passes through a body panel, such as floor,
toe-board, or firewall, provide protection for the
cable to prevent chafing. At the indicator, put a
tag on the cable to identify it as channel 1.
6. Next, route the cable from the trailer (channel 2)
transmitter to the front of the trailer and locate a
place for the trailer half of the cable connector.
Install the cable on the connector and fasten the
connector to the trailer.
7. Install the other half of the connector on the
forward portion of the cable and route the cable
into the cab for connection to the indicator.
Observe the same precautions as in step 5, above.
Identify the cable as channel 2.
8. Secure the cables in the cab, next to the indicator,
and cut them to the proper length for connection
to the indicator. Be sure and maintain the channel
identification.
10.6 Routing the Power Cable
The power cable must be connected
directly to the batteries. DO NOT connect
to an accessory terminal on the ignition
switch, fuse panel, or behind the dash. The
indicator must have a “clean” source of 12
volts.
1. Route the power cable from the batteries to the
indicator.
DO NOT connect to the batteries yet.
2. Observe the previous precautions about
protecting the cable from undo chafing and
abrasion.
10.7 Connecting the Cables
1. Carefully cut back 1 inch of the outer insulation
on the indicator end of each cable. Do not cut into
the white or black insulation of the signal wires
or the red or black insulation of the power cable.
2. Strip off 1/4 inch of the individual wire
insulation.
3. Install the wires into the green indicator
connector and snugly tighten each terminal. See
Figure 10-1.
Figure 10-1. Indicator Connections
4. Review all of your installations and cable
routings, looking for unnecessary loops, tight
bends or kinks in the cables, properly inserted
connectors, and connection of the trailer cable.
5. Connect the battery end of the power cable to the
batteries. Use an inline fuse holder with a 3-amp
slow-blow fuse. Put the fuse holder and fuse in
the red wire and next to the positive battery
terminal.
6. Make sure you are connecting to 12 volts and not
24 volts.
10.8 Final Step
1. Position the indicator plug for insertion into the
back of the indicator. Insure that the screws for
the connector terminals are visible on the top
side. That will position the red battery wire next
to the edge of the indicator case. Verify by
looking at the label on the back of the indicator.
2. Insert the connector into the indicator by gently
pushing straight in.
3. At the front of the indicator, press the Power key
in the lower right hand corner of the indicator
front panel. The information display, above the
softkeys, will first show POWER ON and then
show the indicator model and the software
version. During this time, the indicator is also
performing an internal self-test which includes
briefly lighting all of the small red indicator
lights. If the information display shows any error
messages, see “Troubleshooting” on page 9.
