Mr. Pinball Tip:

Tracking down intermittent problems may be made easier with this trick. For a machine that went into a slam mode, I wondered if there could be a specific combination of events that caused the problem. I couldn't follow the ball as it moved too fast so I caught the problem on video by taping play with a camcorder mounted on a tripod and playing the tape in slow motion. I was able to determine that when the right flipper was energized, a target switch was closed and another target was hit, closing another switch the switch matrix would erroneously read a slam because of a bad diode on one switch. I was able to reproduce the "intermittent" problem and correct it.
