4. If component proves faulty, replace it with a known
working component. If wiring proves faulty, replace it
with wiring of equal gauge.
5. After troubleshooting, test the repaired circuit. Verify
circuit works properly.
Tools for Troubleshooting
The GRT9165 uses a CAN bus Multiplex system. To
effectively troubleshoot the electrical system, use the
diagnostics functions on the RDM. Descriptions for the
diagnostics codes can be found on the Manitowoc
Diagnostic Code smart phone application. You can also use
a Windows-based PC, CAN-link service software, and a
connection cable. The information about the diagnostics
functions, the CAN-link service software, and connection
cable are available through Crane Care to service
technicians who have attended the Grove New Technology
training course.
Swivel Electrical Troubleshooting
Many crane component electrical troubles can be traced to
the electrical swivel. Common swivel problems are improper
mounting, foreign material between brushes and slip rings,
worn brushes, improper brush assembly spring tension, and
loose setscrews on the slip ring assembly. Refer to electrical
schematic and wiring diagram for slip ring connections and
amperages.
Connector Troubleshooting
Cause of an electrical problem may be a loose or corroded
connection in pin or socket connectors. Check connectors to
ensure pins and sockets are properly seated and engaged. If
pins and sockets show any signs of corrosion, use a good
quality electrical contact cleaner or fine sandpaper to clean
them. When pins or sockets show signs of arcing or burning,
replace them.
Refer to the following tables listing required tools for
connector maintenance.
Pins and sockets are crimped to the wires and cannot be
removed. Remove pins or sockets from plugs or receptacles
using an extraction tool. Cut wire as close to pin or socket as
possible. After cutting off pin or socket, the wire may be too
short.
Using a wire that is too short will apply tension to the pin,
socket, or wire where they are crimped when pin or socket is
inserted in a plug or receptacle. Add a short length of the
same size wire to the short wire by crimp splice or solder.
Use heat shrinkable tubing or other suitable material to
insulate the splice.
