Terex PT30 - Electrical System and Storage Procedures

7.21 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 on the left side of the engine compartment.
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.
