Whoaaaaaa, fuse/breaker panel is overhead, but before you turn the first turn on the thumbscrews, articulate your tractor just about all the way to the left.

go to the back rear cab corner outside, there should be a somewhat triangular tin shield remove it (providing it hasn’t been removed already) under (or above actually) the shield there should be a relay/solenoid, some bulk head connectors and some ground wires.

check all of those connections. I believe the power supply for the implement plug comes from the relay but I don’t exactly remember.

that’s one of the places I’d go first, secondly check the wires going into the back of the plug, alotta of bad can go on under that rubber boot thingy.
