If ANY of the tests performed above fail then a problem exists in the initial wiring of the remote controller within your machine.  Damage may have already occurred to the machine circuit board and that can be tested by the following means:

1.  Remove all wiring from the circuit board. 

2.  Measure resistance between terminals #1 and #2.  Meter polarity does not matter.  An indication of less than 20K (2,000 ohms) indicates damage to the machine board output transistor. 

3.  The machine board must be repaired and erroneous wiring of the remote control within the machine must be accomplished prior to installing the repaired circuit board.
