o Disconnect lead AAB from the conveyor control switch. Place the
multimeter red probe in the switch and ground the black probe
Set the MASTER switch to the ON position, the
conveyor control switch to the OUT position, and test for
If no voltage is indicated, replace the conveyor
control switch. Assume the multimeter indicated voltage, set the
MASTER switch to the OFF position, reconnect lead AAB to the
conveyor control switch, and continue to troubleshoot the system.
Lead AAB Test Point.
o Disconnect the gage panel connector. Test for continuity with a
multimeter by placing the red probe on connector pin A, the black
probe on pin B of the hydraulic gage panel mounted connector, and
place the conveyor control switch to the IN position (Fig. 45).
If the multimeter remained on infinity, the lead AAA between the
conveyor control switch and the hydraulic control panel must be
replaced. Assume the multimeter indicated 0 ohms and continue to
troubleshoot the system.
