7.22 Electrical System
The electrical systems in PT machines are equipped with fuses that help to pro-
tect the electrical components from damage. They are found in the fuse panel
enclosure which is located behind the panel cover in the right rear corner of the
interior of the cab behind the operator seat.
In the event of an electrical malfunction, check the fuse panel. Remove the fuse
related to the component that is not working properly and inspect it. If it appears
damaged in any way, replace it.
