The camera power supply has failed on my old Response TV2000 system. The problem is that the power supply has a female DC plug socket to accept a cable from the camera, whereas most power supplies have a trailing cable and plug to connect to the relevant appliance.
Since I've not been able to find a similar style of power supply (i.e. with a plug socket onboard), my best option seems to be to strip the DC plug from a conventional power supply and to connect the bare wires to the lead from the camera. The problem is that the DC plugs are moulded so I can't tell which cable is +ve and which -ve.
Can anyone recommend a good way of finding out which cable is which??
