Hello, I have the above excavator and the control panel ( dash board readout) and AC and some other electricals wont activate. Some are still working, including the lights and wipers. I have checked all the fuses and they are good. I have pulled a couple of obvious wiring harness connections apart, they look clean and I re assembled them. This machine has done this before and then stared working properly again, its a bit of a mystery. If you have any ideas I would appreciate to hear from you, thanks Michael.
Maybe, this will help. If your missing functions, it could be you have a faulty relay. 15A or 15B depending on what works and what doesn't.
