Refer to Figure 10
1. Remove the solenoid cover to gain access to the so-
lenoid terminals.
2. Mount the control box on your tractor. Connect the red
wire (1) to the positive terminal of the 12 volt battery
and the white wire (2) to the negative terminal. You will
need to pull the red and white wires out of the black
harness (3) until there is enough wire to reach the bat-
tery.
Note: You may want to attach the battery leads (4) to the
battery terminals and the control box power leads so that
the control box can be disconnected easily.
After the power leads (1) and (2) are hooked to the battery,
you should be able to turn on the master switch and see
the red power light come on. Turn the master switch OFF
BEFORE proceeding to the next step.
3. Attach the electric solenoid cord (5) to the solenoids
as shown. The green wire attaches to the front sole-
noid {front being toward the hitch}. The yellow wire at-
taches to the middle solenoid and the brown wire
attaches to the rear solenoid. Connect the other wire
{white} to all three solenoids.
4. Hook up the electric solenoid cord (5) to the solenoid
plug (6). You may need to use the extension cord in-
cluded to reach the solenoid valves more easily. Turn
the master switch on and flip the boom section switch-
es to see if the solenoids are operating properly. The
left boom switch should operate the front solenoid, the
center boom switch should operate the middle sole-
noid, and the right boom switch should operate the
rear solenoid. If the switches don’t correspond with
the correct solenoids, check your electric cord assem-
bly in Step 3, or the wiring of the control box under
"Control Box Wiring Assembly Instructions" on
page 20.
5. Attach the electric ball valve cord (7) to the terminals
(8) on the electric ball valve.
6. Hook up the electric ball valve cord (7) to the ball valve
plug (9). You may need to use the extension cord in-
cluded to reach the ball valve. Turn the master boom
switch and flip the pressure adjust switch. The ball
valve should operate when the switch is flipped.
