Electrical Components Check
NOTICE!
If fuses fail frequently, the wiring harness must be
inspected for broken or damaged wire insulation
or a component placing a high electrical load on
the system. Contact a SANY dealer for more
information. Failure to follow this notice could
damage the machine or cause it to operate
improperly.
• Check the fuse panel for blown fuses, fuses of incorrect
amperage, open or short circuits, and loose
connections. Replace blown fuses and fuses of
incorrect amperage rating, and repair loose
connections as necessary. See “Fuses and Relays” on
page 3-23.
• Make sure the battery cables and wires are clean and
in good condition when inspecting the battery, starting
motor, and alternator. See “Check the Batteries” on
page 5-43.
• Clean the area around the battery of combustible
materials.
For additional information about troubleshooting faults in
the electrical system, contact a SANY dealer.
Check the following electrical components:
• Monitor operation.
• Blown or loose fuses.
• Make sure the fuses have the proper amperage
rating for each circuit.
• Make sure the battery terminal connectors are
clean, secure, and free of dirt and debris.
• Inspect the electrical wires and cables for worn or
damaged insulation.
• Make sure the vents on top of the batteries are free
of any dirt or debris.
