Mr. Pinball Tip:

Here's a quick way to test the Molex plugs on Ballys:

Use a paperclip. Just open one end, and pry it into the holes of the suspect molex plug. You should feel a little resistance. When the clip will move in and out freely, you've found a bad connector.

Next to acid damage on the MPU board, this is a very "popular" problem, at least on my Ballys! :-) Guy
