Most of the individual control circuits are protected by a variety of fuses found
in the main fuse blocks located in the operator's control console. A number of
in-line fuses are integrated into the machine wire harness; refer to
(page 6–13). Machines with a cab include additional control circuits protected by
fuses found in the cab power supply harness and in the cab fuse block located
in the cab control panel. Machines with optional lighting kits include additional
control circuits protected by fuses found in a fuse block located in the steering
column control pod, and in the lighting kit wire harness. Refer to
(page A–1) for specific circuit information.
