Hey, sorry to hear you are having these problems. I know that can be frustrating. Hopefully, we can get you back to work quickly. I see no one could help you earlier, and I hope this is not too late to be helpful. Please note that I am not set up for phone calls, you can ignore the site pop-ups. We can post to this chat as much as you like to work through this issue. All experts are not employees, and we work from home in our spare time to answer questions.

Is this a CAT Backhoe Loader? If so, we really need the serial number due to all the different configurations used in building the D series.

I am guessing this one has the solenoid control, try inspecting the frame on the inner right side by the battery box and next to the engine. Some had the solenoids and relays mounted there and they got damaged easily.
