Hello, unfortunately this problem appeared on my Cat 305C CR excavator. I tried the solenoid and the relay but both work during the test. the fuse is also fine. does anyone have a wiring diagram or any other ideas on what to look at? the contact to the solenoid is also fine.
Just wondering, did you find a solution? Have the same problem and suspect the solenoid is bad.
If you want an electrical schematic to assist in your diagnostics then a Serial Number is key.
