It sounds like a power problem. I have little knowledge in electronics, but are you sure it is ok to use 13.8volt power supply? The board requires 12v. A safe bet is to use yellow (12V) and black (Ground) cables from any PC power supply.
As for the wiring, someone mentioned here that "+" "+" and "-" "-" holes are the same and you can run the board with only two cables used. The reason there are four holes is most likely the ease of paralleling power for multiple boards installation.
