hi steve, there should be no reason why you cant fix the issue or at least fault find the issue. obviously if you can claim on insurance that would be best. i would be taking photos of the panel to indicate/remind you of the way it was before you have a go of fixing it. i would then just compare this panel to another level and copy the wiring. what sort of control is it? serial data ie does a cable go to a pcb the wires from it or is it just normal wiring? i would test it this way and then if you wish you can at least know what wrong and then put it back the way it was for the powers that be to decide what to do contractually. try this and see how you go.
