● The white wire (
+
) ends at a plug that is plugged
into the Main Cable Wiring Harness. If the relay is
working, voltage will be present at the plug when
the engine ignition switch is in the “ON” position. No
voltage should be present when the ignition switch is
in the “OFF” position).
● The black wire is attached to the frame for negative
(
-
) ground.
See Figure 21 for the wiring color codes for the relay
socket
The relay wiring harness plugs into the main electrical
harness at the front of the 1530. Check the connector,
Check for damage, cuts, corrosion, or improper fit.
MAIN CABLE WIRING HARNESS
(See Figure 20)
The main electrical harness provides electrical
distribution through connections with the relay wiring
harness, manifold wiring harness, and the hand-held
ON/OFF switch wiring harness. The main electrical
harness starts at the front of the 1530 and ends just
inside of the front of the top dresser’s frame.
The black wire is attached to the frame and provides the
negative (-) ground for the 1530 electrical system. The
red and white wires (+) are (with male connector plug)
connects to the red and white wires from the hand held
ON/OFF switch wiring harness.
MANIFOLD WIRING HARNESS
(See Figure 20)
The manifold wiring harness provides electrical
connections from the hand held control box wiring
harness to the manifold valve block (solenoids S1 and
S2).
The male connector (green and black wires) connects
to the female connector (green and black wires) on the
hand held ON/OFF control box wiring harness.
The two connectors on the other end of the harness
plug into the solenoids on the manifold valve block.
The connector with the black and green wires
black goes to solenoid S1. The connector with the
black and black wires goes to solenoid S2. The
black wires from both connectors are attached to
the 1530 frame to provide ground (
-
) for the circuit.
The hand held control box switch must be in the ON
(
I
) position (for both the conveyor belt and the spinner
assembly) to test for voltage at solenoids S1 and S2.
During operation, when the solenoids are activated,
they close the valves allowing hydraulic flow to power
the hydraulic motors. No electrical power is present at
the solenoids when the hand held switch is in the OFF
(
O
) position.
HAND HELD ON/OFF CONTROL BOX WIRING
(See Figure 22)
The hand-held ON/OFF switch controls the electrical
power to the manifold valve block solenoid valves. ON/
OFF switching is controlled by the switch interrupting the
power to the solenoid. All wires in the switch are positive
(+). Refer to Figure 22 for the proper color coding to
rewire the control box switch. The terminals on the
bottom of the switch are numbered for identification.
Verify that the power supply cable is unplugged before
opening the switch box. Never disassemble the switch
box with electrical power present at the switch. If the
terminals are accidentally shorted out, damage the
electrical components of the manifold valve block will
occur.
After reassembling the control box switch, check
the operation of the switch. The switch must operate
according to the decal. Check that the “
I
” and “
O
”
(ON/OFF) position of the switch matches the “
I
” and
“
O
” positions of the decal on the holder, and that the
1530 conveyor belt and spinner assembly operate
accordingly. If operation is in reverse of the decal, check
that the switch housing has not been reinstalled up side
down. If the housing is in the correct position, remove
the switch and rotate 180° degrees. Reinstall and check
for proper operation.
