Customer Question

I have Dynapac 362d that the engine runs fine until you start to move hydro lever to make machine move. Problem is intermittent, sometimes it will run fine for hours. fuel filters have been changed and a new suction fuel hose installed and fuel tank drain and checked for debris. I also don't have any codes.
JA: What is the complete model and serial number of your machine?
Customer: Model 362D, Pin #10000117L0A009659
JA: Anything else you want the construction mechanic to know before I connect you?

Thanks for the update. Is it throwing any errors or faults on the display?

Customer: replied 8 days ago.
No there are no errors or faults.

Thanks for the info. Id take a close look at the wiring harness and connector pins for corrosion , damage or loose connections including all grounds. Try a wiggle test on the wiring to see if you can duplicate the problem. When it dies see if you lose power to the fuel shutoff or if there is still power indicating a faulty shutoff. Let me know

Hi, did you get this resolved?

Customer: replied 4 days ago.
No suspect it has a time related safety shut off mechanism due to the 4 second time it takes to shut off

I found a parts manual that will likely be helpful in identifying the electrical parts and locations.
