Quoted from nick_k:Was messing around with a Mars AE2411 DBV. I got it used from a local operator to use on my AIQ. I ran the cable from the back box to the front. Checked voltages and got 120V up front. Plugged that into the plug under Node 1 up front. Had switch 3, 7, 8 all OFF. Turned game on and did not get the DBV to talk or even turn on. No LEDs on the back. I know it's not the game but something with the validtor. What should I be looking for next?
The black harness on the DBV make sure it’s plugged in tight and in the correct spot
The other end of that wire connects to the white 9 pin connector that’s attached to your machine. And runs to the board that you connected that white and black 2 prong cable.
Have you done all that? Also the 2 prong cable is plugged into the head behind that silver metal shield?
The MEI cable black that connects to the side and runs to the white 9 pin. I’ve had those be bad before where if you wiggle them they will give power but not perfect. I had to get another cable.
