Where is switch #31 Trough Jam on Whodunnit? I don't see it anywhere on the ball trough.

My Whodunnit has been taken over by gremlins. When the first ball is in play and goes into the subway via the phone, sewer, or the upper center hole by the pops, the ball doesn't eject from the sewer drain. Instead, it rests atop the upkicker and a second ball is served up in the shooter lane and shot into play. If I then reach in and grab the ball in play and hold it, the game goes into the "search" mode of firing all of the solenoids. In that mode, the up-kicker for the sewer drain (where the first ball is now residing) does NOT fire, so the resting ball is not kicked out.
If I run the Solenoid Test for that same up-kicker, it kicks the ball out as it should.
Thoughts anyone??
Quoted from Rascal_H:Does the switch for the vuk trigger in test mode?
Yes, the VUK switch works in test. I also tested all of the switches in the subway, ball trough and shooter lane. All of them work. The only switch I couldn't find (or test) is the mysterious #31- Trough Jam.

It seems really odd that the VUK solenoid works in test but doesn't fire during the routine to clear a stuck ball.
Quoted from pintime:FlatsRUs, that's normal for this game .At game start there should be 3 balls in trough and one in sewer.If the ball in sewer was launched during multiball it will store the ball back there the next time it's sent into subway
Wow. I've had this game for a year and didn't know that! Thanks, you no doubt saved me a ton of needless "troubleshooting".
More (self-inflicted?) Whodunnit issues. I did some much-needed work on my Power Driver Board and after re-installing it, I have no controlled lamps. Would someone please take pictures of the J133, J134, J135 connectors to make sure I have them connected properly (they are all keyed the same!!!!)? Also, J120 would be appreciated. Thanks in advance.
Quoted from Mancave:Too Easy
Thanks for the quick pics. I looked at mine and the wiring at J120 and J121 along with J133 and J134 are opposite of yours. I thought that was my problem but in looking at the schematic (and confirming with a DMM) they are keyed the same and are truly parallel connections (J133, J134 and J135 are triplets). Additionally, J137 and J138 are twins. Further investigation led to the discovery of no 18v on the power driver board. I had just replaced the header connector at J121 and all of the caps, including the 15,000 uf caps at C6 and C7, so I no doubt messed something up. Back to the workbench!
