Not sure about that wiring but you need to ajust the eddy board with the small pot.

I was having the same issues and replaced the eddy board with the pinbits eddy board and never looked back. An absolute must for this game IMHO.

That extra wire needs to be plugged into the board in the 2nd picture. Male plugs are on the top side of the board.

You need to turn the Potentiometer just above the led in the second picture until the light comes on - JUST comes on - should be a very small adjustment.

Then when it senses a ball rolling over the PF where that sensor board is, the light should go out and it should register a hit.

I haven't done this in a while but I think it's the other way around. The light should be just off and come one when the ball is near.

Yeah, now that I think about it, you're right. I haven't done it in forever, either.

So he'll want to adjust until the light comes ON, then back off a tiny bit until the light JUST goes off.

I can't tell from the pictures but if I remember correctly there are two sensors for Ted and one for Red.....what are the wire colors and try to match it with the manual..

Okay, then you seem to have an extra eddy sensor, (they are all wired with a blue pair of wires) that needs to go to one of the three eddy sensor circuit boards.....You also need to download the manual...
