To check voltage reading of a Komatsu PC200-3 excavator’s main pump solenoid, a voltmeter would be needed. The following are the steps:
- Switch off the engine and remove the battery cables to avoid any incidental electric discharge.
- Locate the excavator’s main pump solenoid which is often situated close to the main hydraulic pump.
- Put your voltmeter on DC voltage and attach its positive lead to the wire of the solenoid as well as negative one to any ground source.
- Switch on ignition but don’t start engine yet.
- Read voltage with your voltmeter. Voltage should be within range stated in manufacturer’s manual.
- If it is out of range, then it suggests that there could be something wrong with solenoid and it needs to replace it.
It should be noted that specific model of Komatsu excavator may have different exact voltage reading for main pump solenoid. Always refer to manufacturer’s instructions and consult professionals if need be.
Even though participating in online forums for troubleshooting purposes can give you some useful information, caution must still be exercised so that whatever info you get from unverified sources could be authenticated. Should you have any problems with your Komatsu PC200-3 excavator, it might just be better seeking a qualified technician or mechanic’s help.
