Alright club, I could use another pair of eyes on this issue. I am wrapping up my restoration and I am finding that when whirlpool is lit, I am getting phantom whirlpool mode starts.
Some things to note:
- When I get a phantom whirlpool mode start, the big foot diverter does not fire. So I feel like that rules out both switches associated with the upper whirlpool ramp.
- The above lead me to wonder if the issue is where the ball drops into the subway and trips the opto. Upon inspection, the metal piece where the opto is attached seems to not be very secure, so I used a zip tie to better hold it in place:
However, the issue still persisted. I did some more play testing and found that hitting it in the pops and the slings seemed to draw the most phantom whirlpool mode starts.
Next, I unplugged the above noted opto and play tested again. The issue stopped.
Dirty opto? This thing did sit in my parts bin for a month in the garage.
Let me know if there is anything else I should consider. Will try cleaning them tomorrow.
