Control Box Wiring Assembly
Instructions {Manual Control System
Only}
Refer to Figure 11
The electrical assembly schematic is shown for the con-
trol box in a view that is looking into the back of the box
with the cover off. There are four separate wiring har-
nesses that enter into the control box along with the
positive and negative power leads. In this control box,
the red wires are always positive and the white wires are
always negative. Other colored wires could be positive
or negative. Make sure that all wires are attached as
shown in the schematic. There are two wire nuts that at-
tach several wires at once and are displayed by the large
asterisk (*) signs in the drawing.
Attach the wires as shown in the drawing for any electri-
cal repair work. This will also serve as a guide for
replacing the electrical wiring. Refer to "Sprayer Con-
trol Box Assembly" in the parts manual.
IMPORTANT
: Disconnect battery leads before
working on any electrical components in this control
box. Failure to do so may result in damage to the
electrical components.
