First off, there is no ghosting during attract mode and Comet non ghosting LEDs used. Coin up a game and the yellow light on the main traffic light starts flashing along with the green. Maybe with the flip of the bats, other lights starts flashing like the 1,000 lamp at the kick out, the stoplites light escape lamp. Seems to coincide with the sound solenoid. Also, more as the game is played, and more the points are racked up, the more lights that start flashing when they should not. There is not a pattern to this other than the first light to come on is always the yellow light on the main traffic light.

Is there a lamp matrix for this game? I have not seen one yet. Any ideas on where to start to look for this problem?

Well, I did find a lamp matrix.

With the main traffic light unplugged, the ghosting is gone. That is till I plug it back in.

Well, I got good news. Messed around with the traffic light and plugged it back in seemed to have fixed the problem. I have no idea what I did, but it's working now.
