I'm trying to add a spot light to my Saga Lost In Space aimed at the Robot using a 555 size spotlight housing and a Cointaker 555 LED super bright LED. I've got it installed and both wires of the spotlight is wired to each side of a controlled under playfield light. This light comes on when Robot Multiball is ready so the spotlight comes on and shins on the robot when this mode is ready.
Here's the problem; the spotlight will also come on when other controlled lights on the playfield come on and these other lights also come on when the spotlight is on. I did a Column/Row test on the light circuit. On the Row test all lights come on (including the spot light attached to the controlled light attached to) at the proper times. The problem manifests when I do the Column test.
Is the problem with the way I have it wired up or am I using the incirrect Cointaker LED? Maybe I should be wiring this setup in series and not parallel?
Thanks for the help and any suggestions,
