The red light on the Power Distribution Board comes on to tell you there's something connected to the Wago terminals, but the breaker is either missing or tripped. The clicking is definitely the breaker tripping and resetting. I expect the breaker gets rather warm when this is happening.

Double- and triple-check the connections to the Jaguar. If nothing looks wrong, my suggestion is for you to remove the wiring on that branch and replace it along with the Jaguar itself. It's only two wires, right?
