Here is a link to good video on coin mechanisms.
I determined why the coins where being diverted to the coin tray by the coin mechanism. But haven't figured out how to make the adjustment.
The coins were being pushed to the opposite / right side and dropping through. I determined with the slightest bit of resistance on the coin it would work fine.
So for a quick fix I added some tape and it works most every time.
On the back of the unit is an adjustment with light flexible metal that the coins make contact with. They look like deflectors for other coins, but not sure.
So, looking for solution to slow the coin and or deflect it to the right coin slot. Instead of Blue Tape as that won't last.
