Ever since I got my TAF I have had problems where more than one lamp blinks sometimes. The lamps in question are either in the same row or the same column in the lighting matrix.
For example... I am testing Thing Multiball lamp, I also have lit Jackpot (same column), Light Advance X (same row), and Shoot Again (same row as Jackpot, same column as Light Advance X.
or
Testing Extra Ball, I also have lit Jackpot (same column), Right Special (same row) and Shoot Again (same row as Jackpot, same column as right special)
When I test Jackpot, only Jackpot lights.
As I write this I realize that when other lamps light one is in the same row, one is in the same column and one is the junction of the two other lamps that lit.
I figure these must be controlled through the wiring coming from J133 and J137 since when I unplug either of these all of the lamps go out. I unplugged from the board and tested each pin individually when Thing Multiball was supposed to be lit. I get the same voltage out of every pin in the same molex all the time.
I am sure this is pinball 101 and I should know how to do this, but unfortunately, I do not. Please use non technical words and maybe use photos as well since I probably don't know where to locate half of the stuff I should be testing.
Thanks in advance for any help you can offer!
