LS2 not selecting

[paradisecs]

I have a LS2 that I had the pricing unit, selection assembly, coin mech,  scc, tsa, service switch, wire harness, and mech all removed and on my workbench to work on.   I'd only worked on the microlog units until this one so it was a big learning curve.  I got the unit up and running great on the bench after rebuilding the electronics and tearing down and cleaning the mech.  After moving everything back in to the cabinet the unit won't make selections.   I hear the credit add when I drop in a coin but pushing the selection keys is dead quiet, no solenoid activation.  I've checked the voltages on the SCC and they seem to be within tolerances.

If it was working out of the cabinet I've obviously done something wrong putting it back in.  Could this be a problem in the wire harness or could something have happened to the UDP in transit?  It seems like I have an open ground but I'm not sure where in the system that would cause this.

Hi,

I hope all is well.

Just curious, did you figure it out?

Not yet. I got frustrated and moved it back to storge while I started a new job teaching introductory electronics. My plan is to get it back out once school lets out.
