the six screws with wires on them on the ev100 card are inputs to the card that have to be 'made' in a correct order. tell us what the voltage is, starting with the left-top screw as 1, and go across to 3, then start as 4 the left bottom row (the last 2 are inputs from the directional switches, so let us know what direction is selected). we can then shorten the list of what is "dropping the ball", so to speak.
as far as what is left and right on the card, depending on how the card is mounted, the 2 smaller plug in connectors are on the left (we call them A&B plugs) and the 2 larger on the right (we call them Y&Z)
