grounding the black probe (Fig. 41). If the multimeter indicates
no voltage, lead 10 to the hydraulic control panel is defective
and you must notify support maintenance.
If the multimeter
indicates voltage, set the MASTER switch to the OFF position,
reconnect lead 10 to the gage panel, and continue to troubleshoot
the system.
Figure 41.
Conveyor System Panel Connector Test Point.
o Disassemble the hydraulic gage panel.
Disconnect lead 10 from
the conveyor control switch, place the red probe of the
multimeter in lead 10, and ground the black probe (Fig. 42). Set
the MASTER switch to the ON position and test for voltage. If no
voltage is indicated, lead 10 is defective between the conveyor
control switch and hydraulic gage panel connector and must be
repaired. If the multimeter indicated voltage, you must continue
troubleshooting.
Assume the multimeter indicated voltage, set
the MASTER switch to the OFF position, reconnect lead 10 to the
conveyor control switch, and continue to troubleshoot the system.
o Disconnect lead AAA from the conveyor control switch. Place the
multimeter red probe in the switch and ground the black probe
(Fig. 43).
Set the MASTER switch to the ON position, the
conveyor control switch to the IN position, and test for voltage.
If no voltage is indicated, replace the conveyor control switch.
