Quoted from billsfanmd:Finished shopping and it looks great. Of course now I have an entire switch column out. Makes no sense. It's the column with the 5 ball trough switches. Green red wire. I get continuity from all switches in the colmn Has to be on board connector? Any other reason I would lose this colmn. I did not touch any switches in this column and it was working perfect. I have to say the wiring under pf is very organized and tightly secured. Any ideas ?
This is a common issue on DE's, and is a result of a 4404(? - I likely have this number wrong, looks like a pre-driver transistor) transistor for the columns. Almost every column issue I have ever dealt with on DE's is a result of this.
For column/row issues, I start with checking when it first connects in daisy chain to the PF, as if there is an issue there, as with lights, you'll see it all the way down, but otherwise confirm which transistor does this column, and check with a DMM. <

I've thought of removing the one, but I thought the hole would be too big to stop the ball from coming out possibly on hard hits.
I've said it before, but the key to hitting this when the ball is at the lower flippers is trying to bank it off the left post or drop target (if up) of the center bank. You get way more chances, and in MB, once going for the super there, just start launching balls in that area, and you are bound to hit it.
Trying to set that shot up from the upper is next to impossible, and even when it trickles down to there perfectly, it's still a crap shoot.
