Trying to troubleshoot a friend of mine's Whitewater. Every once in a while, when you hit the green stand-ups in the center the game crashes. See the video below. Any ideas?

Pretty sure it's always the right of the two green stand-ups. Doesn't happen every time though. Very sporadic.

I'm kind of a newbie, but it looks like it's the "light lock right" switch and it doesn't look on in the diag best I can tell.

It says rev L-5 on the service menu. Is that what you mean? Again, newbie. Sorry about that and thanks for the help!

LTG, it was definitely wired reverse from the rest. Just rewired it. Fingers crossed!!!

Well, consider this another day officially saved! Played a bunch more, slamming on that stand up with no resets. Thanks a million LTG!!

Amazing! It was totally demoralizing when you were having a good game and just crashed out.
