The power cable on my Dolphin Dynamic 3002 has become detached from the amphenol connector. On inspection, there are three wires, not the reported two. Can anyone tell me the correct positions for the wires? the connector has terminals marked 1,2,3 and a blank one. The wires are red white and black. I presume black and white are live and ground,
ADMIN REPLY: Most power supplies have 2 screws holding the socket. Pull out the socket and wire the plug to match it.
