The problem I am having is that sometimes the drop targets on the mini-playfield don't work, but other times they work just fine. This has been an on going problem since I bought the machine. The previous owner told me about the issue, and for a while now I thought I had it fixed. The problem has resurfaced.

After I got the machine I removed the DT-bank, completely disassembled, cleaned, reassembled, and replaced the opto board with a new one from Great Lakes. After reinstalling the bank, the issue was still present for the first three games, and then it went away and everything was just fine for the last 9 months or so.

The last few days I have been cleaning and prepping the game for Allentown. After doing an adjustment of the settings the problem came back. It usually starts with drop target relays firing like a machine gun for no apparent reason. Now the problem is random as to when it happens and when it goes away. Its starting to be more that it happens. One thing I have also noticed this time that I never noticed before, is that the insert lights and display will flash at a higher rate then they do normally after the coils fire randomly.

Any suggestions or ideas to fix this? Like I said the Opto board is new, and the coils definatly work so I am thinking its something somewhere else causing the problem. Maybe a loose harness somewhere? Another driver board that is not working right? Would like to figure this out before A-Town as I am bringing the machine and would like it to be working 100%.
