Hi ther everyone. I have tinkered with my Dolphin quite a lot. Opened all parts etc. The one thing that has me stumped is how to change and replace the side panel with the cord running through it? The hole in the panel is too small to get the wires at whatever end I try out form the hole. I have disconnected the plugs from the motor it just does not go through. There must be some way to get the cord out? Anybody got ideas?? Thnaks.
