OPERATING INSTRUCTIONS 6015 / RH40E Inspection and servicing ELECTRICAL SYSTEM Electrical system - Safety instructions
Alternator - Instructions Never disconnect cables from the alternator, regulator and the battery when the engine is running to avoid damage to the alternator and regulator.
Risk of injury caused by battery acid and gases.
Do not interchange the cables when connecting the battery (observe polarity).
Read and observe the "Inspection and servicing – Safety instructions" chapter.
Carry out voltage and continuity checks only by means of a test lamp or a measuring instrument. Do not check by "touching ground" with a bare wire. The short-circuit thus produced damages the alternator and the regulator.
Wear goggles, working gloves and firm working clothing.
Cables and cable lugs must not get in contact with other metal parts. Replace broken or damaged cables and the respective cable lugs.
Carry out voltage and continuity checks only by means of a test lamp or a measuring instrument. Do not check by "touching ground" with a bare wire. The short-circuit thus produced damages the alternator and the electronic modules of the PMS.
Electrical circuit diagrams The electrical circuit diagrams and wiring diagrams are annexed to the spare-parts list. Further information can be found in the Bucyrus HEX Technical Handbook "Working with circuit diagrams".
Electrical system switch-cabinets The electrical system switch-cabinets are located in the cab module, in the pump compartment and behind the hydraulic reservoir. The cabinets are described in the spare-parts list (electrical circuit diagram) together with the designation of the electrical components. Fuses and their function are listed on a sheet inside the switch-cabinets in the cab module.
Replacing lamps and bulbs If a bulb does not work after replacement, the pertaining fuses, connection cables and contacts must be checked. Xenon-working floodlights are operated with high voltage. Read and observe the chapter: “Floodlight projector, replacing the lamp”. Floodlights working with LED-technology do not have replacable lamps / bulbs. The floodlight must be replaced if defective.
