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 additional information.
• The top of the battery must be kept clean to prevent plugging of the battery vents.
Regularly wash the top of the battery to prevent battery vents from plugging.
Failure to follow these notices may cause damage to the machine or cause the machine to
operate improperly.
Check the fuse panel for blown fuses, fuses of incorrect capacity, open or short circuits, and loose connections.
Replace blown fuses and fuses of incorrect capacity, and tighten loose connections as necessary. See "Fuses" on
page 5-28.
Make sure the battery cables and wires are clean and in good condition when inspecting the battery, starting motor,
and alternator.
Clear the area around the battery of combustible materials. For more information about faults in the electrical
system, contact a SANY dealer.
