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

materials.
For additional information about troubleshooting faults in
