numbers from the LSS harness to those of the Host
Control System.
10. Install the Overload Lamp at Ground Control if nec-
essary. Open the Main Terminal Box and ensure that
the Overload Lamp is installed in the Indicator Panel.
Alternately, observe the Ground Con-
trol's Indicator Panel for the Overload
Symbol during Power-Up with the Key-
switch in the Ground position. If it is
present, skip this step in the procedure. To install the
Overload Lamp, first review the AMP Connector sec-
tion of the vehicle's Service Manual for detailed
instructions regarding the connector system.
Next, mount the lamp by inserting it into
the opening behind the Overload Symbol
and rotating it until it locks. Route the
lamp's Brown/White and Black wires from
the door toward the Ground Module's J4 connector
and secure with wire ties. Remove the J4 Connector
(Blue) from the Ground Module by releasing the
locking tab with a 3/16 inch (4.8mm) wide screw-
driver blade. Pry the red wedge lock to the open
position for contact loading, but do not remove it.
Remove the sealing plugs with a small pair of pliers
by rotating them back and forth during removal.
Insert the Brown/White wire into J4-14 (lamp output),
and the Black into J4-32 (ground). (If J4-32 is
already used, connect the Black wire to the ground
on the last indicator lamp in the chain.) Close the red
wedge lock by squeezing it uniformly inward. Install
the J4 connector back into the Ground Module and
ensure that the locking tab clicks into position.
11. Setup the Host Control System to enable the Load
Sensing System. Power-up the Host Control System
by resetting the EMS at the Ground Control station.
Plug the JLG Analyzer into the Host Control Sys-
tem’s Analyzer Connection at the Ground or Plat-
form (do not confuse the Host Control System and
LSS Module’s Analyzer Connections).
