Did you move the jumper settings on the Electrical Selector? If you have the manual I recall it’s outlined when adding a stepper.

If not I can scan that page and email it to you

Hi, I installed a rebuilt RCSU3 stepper in my 222 Seeburg. (It replaces the TJU2 Tormat Junction Unit). My Tormat Selector is Type TSU1...Code A) Once installed the jukebox will not play any selections ending with the number "1" (A1, B1.....etc.) made from the wallbox nor from the jukebox selection buttons. All other selections work fine. When I put the Tormat Junction Unit back in place of the stepper, all selections including those with number "1" work fine. Stepper units are foreign to me and I can not find much info online. My Seeburg manual has a couple of pages on adjustments but nothing on trouble shooting. I'm thinking that something is not resetting completely or there are dirty relay contacts somewhere. I'm not certain if it matters but the 3-pin plug on the TJU2 has 3 contacts and the plug on the RCSU3 only has 2 contacts. Can someone point me in the correct direction to start looking?
