[Jukebox-list] Another problem child, Wurlitzer 2810 not selecting

I have a 2810 in for some work. Got everything fixed and testing it yesterday it suddenly stopped selecting. It was set on free play when it came in and that worked fine. (It had some funny little clip on the free play button to make it stay on.) It was working perfectly. I had tested it for some time, then suddenly when making a selection, the buttons latch in and that's it. Both latch solenoids are engaged and the associated contacts are cleaned and adjusted. I did go through the troubleshooting menu in the manual but didn't find anything. Any ideas?

Thanks, Tony
