DBV resets WMS reel slots

[corndog]

Hi all,

I am copying my post over from the WMS Reel slots, looking for some extra eyes. Check out the video for the exact bug...

Newbie, first slot machine, Joey at NLG fixed my first PS problem in about 5 seconds. Continuing on with the final bug.....

Finally got the DBV to  accept the bills after a small cleaning of the optical scanner. (Previously, the DBV would loop for about
30 seconds, than stop, would not accept anything, slot would accept coins, no problem.)

Now, DBV will accept bill, all player panel lights go off, machine re-initializes, lights go back on,  DBV spits bill back out.
Machine will still accept coins, plays normally.

Slot is a WMS Model 400 Jackpot Stampede.

I have cleared the ram.

Installed a new DBV-200 from Fannini Slots

Checked the switches at the can and access door.

Plugs at backplane and DBV are good, no broken wires, recessed pins, etc.

Used an ATX standalone power supply for the DBV +12V to isolate the supply, same problem.

Any help is appreciated.

Thanks,

Kevin
