Batteries and Battery Disconnect Switch
Batteries are located in a compartment on the left side of the
crane. Batteries are the maintenance free type and
completely sealed except for a small vent hole in the side.
The vent hole allows a small amount of gases produced in
the battery to escape. On some batteries, a test indicator
located on top of the battery is used to determine if the
battery can be tested in case of a starting problem.
A Battery Disconnect Switch is located to the right of the
battery compartment. To disconnect batteries, turn Battery
Disconnect Switch OFF. Turn switch ON to connect the
batteries.

superstructure relay and fuse boxes, wiring harness
connector bulkhead, RCL module, and the RCL Override
switch.
