How to solve the problem that Sany SY365H-9 excavator has no movement during use? Let’s take a look.
Fault phenomenon:
The SY365H-9 excavator has no movement, the monitor has no display, and the fuse #2 is always blown out.
Fault repair process:
1. Disassemble the CN-H06 connector and measure the ground resistance of pin ④ of the CN-H06 connector. It is zero, which is abnormal.
2. Disassemble the CN-H04 connector and measure the ground resistance of pin ④ of CN-H06. It is infinite, which is normal.
3. Measure the resistance between the two pins of the buzzer to be zero, which is abnormal.
Fault conclusion: buzzer short circuit.
Treatment measures:
It was judged that the buzzer was internally short-circuited. The buzzer was replaced and fuse #2 was installed. The machine was normal.
Treatment experience: Due to the internal short circuit of the buzzer, the PPC lock solenoid valve cannot receive power and cannot be excited, causing the whole machine to have no action.
