The rotating bed ground points are as follows:
• Negative Remote Ground Terminal (1)—The negative
remote ground terminal is located on the battery
disconnect switch panel.
• Rotating Bed-to-Cab Arm Ground Strap (2)—Ensures
an electrical path to ground between the rotating bed
and the cab arm.
• Cab Arm-to-Cab Mount Ground Strap (3)—Ensures an
electrical path to ground between the cab arm and the
cab mount.
• Live Mast-to-Rotating Bed Ground Point (4)—Ensures
an electrical path to ground for electrical components on
the live mast frame. It electrically connects the left arm of
the live mast to the rotating bed frame. A ground cap
assembly (5) provides connector protection when the
live mast is not attached to the rotating bed.
• Rotating Bed Main Ground Point (6)—The rotating bed
main ground point is a ground stud located at the inside
right frame of the rotating bed. The ground stud provides
a single connection point for the ground circuit of all the
electrical devices located on the rotating bed and the
carbody. A ground cable connects the ground stud to the
negative battery terminal.
