What happens here
Alex attempts to operate a yellow SDLG wheel loader to attach a snow pusher, but the quick attach mechanism is unresponsive. Upon inspection, he discovers a blown fuse, similar to a previous incident where a hydraulic valve shorted out due to water getting into the electrical connectors. He removes a black electrical plug from the hydraulic valve and confirms it is wet inside, indicating water ingress as the cause of the short circuit and blown fuse.
Goal: Identify the root cause of the quick attach mechanism failure on the wheel loader.
