My Dolphin Deluxe 4 developed an intermittent in the cable right by the power supply connection. Should this happen to you there is a replacement connector available:

Just cut the old one connector off, strip the cable wires, and attach to the new connector.
NOTE: Be sure to leave enough wire attached to the old connector so you can check which pin each wire connects to.
