I read the steps posted by Barry and read what others have said as well. I did the royal blue wire swap from the 5v PS2 with the Mux board and still to no avail, flickering away with smoke.
Now after doing step one in the four step procedure, lets say I know my limits and called it quits from there 
So knowing the 5v board is still good and working should I have a tech fix the issues or should I just drop a 3v PS2 board into the engine instead? If I go that route does the blue wires need to be swapped back and will the new 3v board address any of this or will there still be an issue knowing that there is still a mux board in the boiler section of the engine?
Thanks in advance.
