CHAPTER 2 MAINTENANCE
1 SERVICING
If you suspect a problem with the alternator, most alternator problems can be
traced to one of the following causes:
• Battery or battery connection fault.
• Loose, dirty, or corroded alternator connections.
• Broken wires to alternator.
• Slipping drive belt.
Before repairing the electrical system, disconnect the positive
cable from the battery to prevent possible injury due to electrical shock.
NOTICE! Before welding on the machine, disconnect the battery to prevent
damage to the alternator.
The operating voltage of the electrical system is 12V.
• Do not disconnect the battery when the diesel engine is running.
• Do not start the diesel engine using a battery charger when the battery has
been removed.
• For electrical welding work, disconnect the battery. The positive terminal of
the welder shall be connected directly to the part to be welded.
An electrical schematic is shown in Chapter 2 Section 2 for reference and an
