16.
Ensure that none of the hoses contact any sharp edges or hot surfaces. Tie-wrap all hoses
securely leaving enough slack for the railgear to function.
17.
Install the In-Cab Control panel in the cab in a convenient location under the dash.
18.
Install the circuit breaker under the hood near the previously installed railgear pump
solenoid.
19.
The pump manifold has three wire harnesses and two wires connected to it:
a)
One 4’ wire harness for the front or rear railgear with a control box on the end.
b)
One 36’ wire harness for the front or rear railgear with a control box on the end.
c)
One 22’ wire harness for the in-cab controls with terminated wires on the end.
d)
One white and one black wire each with ring terminals on the ends.
20.
Using suitable 14 gauge wire, cable loom, connectors, solder and heat shrink tubing:
a)
Lengthen the white wire if required and connect it from the manifold to the switching
terminal on the railgear pump solenoid previously mounted under the hood.
b)
Lengthen the black wire if required and connect from the manifold through the
firewall to the load terminal on the railgear switch on the In-Cab Control panel.
c)
Connect another length of black wire from the power terminal on the railgear switch
through the firewall to the “Aux” terminal on the circuit breaker.
d)
Connect another black wire from the “Bat” terminal on the circuit breaker to the
power terminal on the solenoid.
e)
Connect another wire from the ground terminal on the railgear switch to a suitable
ground location on the vehicle.
f)
Ensure the manifold is properly grounded to the vehicle chassis by connecting a wire
from the manifold to a suitable ground location on the vehicle. The railgear may not
be properly grounded due to paint on the mounting plates and tar on the frame.
g)
Lengthen the 22’ wire harness if required and route it from the manifold through the
firewall to the In-Cab Control panel. Connect the wires to the In-Cab Control switches
as shown.
21.
Using suitable 2 gauge wire, cable loom, connectors, solder and heat shrink tubing:
e)
Connect one wire from the vehicle’s battery to the power terminal on the railgear
pump solenoid.
f)
Connect another wire from the load terminal on the solenoid to the power terminal on
the pump motor. Use the supplied rubber boot to protect the pump power terminal
from shorting out.
g)
Ensure the pump motor base is properly grounded to the vehicle chassis by connecting
a wire from the pump motor base to a suitable ground location on the vehicle. The
railgear may not be properly grounded due to paint on the mounting plates or tar on
the frame.
22.
Route the 36’ wire harness from the pump along the frame to the front or rear of the
vehicle and secure in place with tie-wraps. If necessary, the control box can be removed
from and reinstalled on the wire harness to facilitate routing. Fabricate a bracket and
mount the front or rear railgear control box with installer-supplied hardware in a
protected vertical position in a suitable location.
