I was getting a 7v reading on both lugs of one of the effected lights which made me think at least part of the gi up the left side of the machine wasnt able to connect to ground. I jumped to the ground side of a known working light and the bulbs kicked on. Strangely, when i removed the jump the lights remained on. I jostled all the wires and bases for the lights in question and couldnt get them to go out again…. Marking closed for now.

Per Kris and Deshawn:

checked about lower left general illumination corner and turns out the lower left section is getting ~1/6 of the power than the lower right section, so it may be an issue with the wires.

Replaced all of these lamps.

The left slingshot and lower left lane lights are still not working. Lamps are new and tested so it’s not that.

Also replaced lots of bulbs in the backbox.
