Hi guys, need help badly with this problem. Case 521 loader not moving forward or reverse. After engine starts, buzzer is always on with alarms on cluster as per photo. One button also missing from the cluster. Alarm looks like brake pressure but I measured it once using a gauge ( happened months ago ) and it was 64 bar , so may be it's the parking brake solenoid or pressure switch. Anyone has a circuit diagram for the cluster and the brake circuit please.
Update. It moves now however there is a persisting brake alarm that I don't know how to check.
Check the brake accumulator charge valve
Is it a part of the brake valve body, i have no documentation for this loader
On the bigger machines it used to be on the right side of the machine inside the frame near the engine. I'm not sure if that location is correct for the 521. You could find the accumulator and follow the lines.
