Bowling alley issue: Direct hits to any bowling pins to the RIGHT SIDE of pin #1 (aka pins 3, 6, 9, and 10) don't register as being hit. The ball must pass by the right side of each pin (or just barely glaze the right side of any given one of them) in order for them them to register. The bowling pins on the LEFT SIDE of pin #1 (aka pins 2, 4, 7 and 8 ) do not have this issue. Those pins register 100% of the time on a direct hit.
It's almost as if the "sensoring/triggering" of hits to all pins in the alley is slightly "shifted" to one side or the other if that makes sense.
BTW, this is a consistent, not intermittent problem which has always been an issue with my bowling alley, nothing new. I'm just becoming more annoyed about it these days since I'm entering bowling mode more often.
I'm guessing it's an optic triggering issue not recognizing direct hits to the pins in question, but I'm not well versed on all the optics. The only optic sensors I know about are those on the left and the right side of the alley. I will say that those optics look to be positioned correctly, but perhaps they are not or something else is causing this?
What should I try to adjust or test to fix this issue?
