So I leave both plugs connected and try to get a signal of volts from between the two wires shown in the FSM? The white center wire and the black wire on the grey connector, not the square one on the front of the unit? I'm so confused, the FAQ writeup has no pictures so its no help. I'm not so good at this so I need as detailed a description as possible so I can test it and adjust it. Thanks again for the help. -Eric
