Chased my tail for three days.

This was a real head banger. Finally solved I hope. 🤞 sharing in case others experience the same. Been dealing with an intermittent issue with a bill acceptor in bay 2. For reference these are relatively new Talos acceptors that were part of three new meter boxes I installed in October 2025. Here's how the past three days have been spent. Check all bays in the morning, everything works great, check cameras remotley throughout the day and see the bay in question has been used less than normal. Swing by at lunch sure enough no flashing green lights, won't pull a bill in. Take apart clean, verify voltage, check, double check, bang head, nothing. It wasn't even running through the initial cycle when you slapped the stacker back on or resupplied power. Research, scratch head, research, bang head, repeat head back after dark, boom it's working. (See where this is going) Finally at my wits end this afternoon I take the time to swap it with another bays acceptor. As I'm loosening the hold down nuts it starts to cycle. Not 100% sure I go ahead and swap with another, I notice how much looser the hold down nuts were on the bay 1 acceptor. Best I can figure bay 2 faces the sun, the nuts have been over tighten since the orginal install but now it's 90⁰ here and thermal dynamics took over just enough to cause the plastic acceptor to heat up, nuts were so tight it didn't allow for any flex so it would bind up and fail to function in the mid day sun. Reinstall eveything, made sure nothing was over torqued, seems to be all systems go now.

TLDR: mother nature always wins.
 
Wow, I never would have guessed that, but it sounds reasonable enought to be true! Heat and cold mess with everything!
The coin acceptors on our vacuums don't like to work in the sun, with the door open. They work in the shade.
