I have the Aquarite goldline setup. I had the dreaded crumbling black disc problem. So I ordered two and replaced by cutting off old and crimping a new one on. Apparently I did not crimp one side well enough and it slid down and made contact with the board. I have now removed the old posts and tried to solder on the board but it is not holding. Looking for wiring diagram to know what runs where so I can run some jumper wires. I can see the right post goes to the right - to the red wire. I can not tell where the left post goes. Any insight or guidance would be helpful. Hate to replace the board.
