Change out the connectors (female) with trifurcon pins. You should be good to go If that doesn't do it check the back side of the rectifier board and reflow the solder around the back side of the pins.
That's the fun of having early Bally solid state games. I have 7. Almost as much fun to repair as they are to play.

Best bet is to get with Steve young at pinball resource and tell him what you have and he will send you the pins and he should have the crimper you will need or will tell you where to get one. Screenshot_2015-12-12-19-36-46.pngScreenshot_2015-12-12-19-36-46.png
