Switch on your left flipper assembly, next to the eos. Maybe out of adjustment, or have a wire off. If you neef to afjust, do so with power off as not to short anything.

Left lane change isn't working. Could be an extra leaf blade switch on the flipper button, or EOS, or an opto coupler on a board in the head. Depending what is in your game.

On pinbot, the lane change is on the flipper mech. It is normally open, and closes when tbe flipper is up. This switch is part of the matrix and should be seen during switch test. Be careful that the eos switch high voltage doesn't hit the lane change switch. The lane switch only changes the lit in/outlanes on pinbot, there is also one on the right flipper ( edit: and enter high score initials)
