Power on it starts running selecting record at random, playing them. Never stops running and selecting eve with selector assembly disconnected.I checked all relays everything seems fine . After a couple of day rechecking everything run out of ideas on what to check next. I do have all the documentation on my jukebox from seeburg . Miss my old jukebox.
Did some more checks this morning. The jukebox plays the same pattern of selections i.e. A1 A3 B1 C1 C3 E5 G7 H9 J9 over and over. Anyone know a way to reset this pattern or stop it ? Greatly appreciate your suggestions

It seems like the mechanism may not be canceling 'A' side selections.
I'd check the 'contact block' (under the pin bank) to make sure the plunger in the 'cancel coil' is free.

Dead on, thank you very much. After a few hours of troubleshooting i finally arrived at the same conclusion . Found the selector coil in the 100s3 selector coil and armature assembly to be burned out (304327). Relay never comes on . Appreciate you help.

Make sure you check the adjustment of contacts 'SC' and 'C' on the 'Cam Switch'.
If the replacement coil stays energized it will certainly burn out.

I've replace the cancel coil in the selector assembly. Checked again the SC and C contacts adjustments. The coil will not energize to reset the pins on the selector assembly. The only way i can get it to energize is to physically make SC contacts. Can you tell me where the pulse for energizing the cancel relay comes from? Went over and over in the manual information but it is really vague. Any help from your expertise in this field would greatly be appreciated. Thanks |

If manually making the SC and/or C contacts make the coil fire, the issue is certainly contained to those contacts.
You will have to watch those contacts closely while the mechanism is cycling into the play position.
The SC contact should be normally closed in scan position.
When the mechanism cycles into play, the C contact will close keeping both contacts closed momentarily until the continued movement of the switch blade opens the SC contact.
It's possible that the contacts need cleaning/filing/burnishing if they are not making correctly.

Also, don't discount using the search feature on this forum. A quick search turned up this post: jukeboxaddicts.proboards.com/post/23350If it's a Seeburg issue, it's probably been addressed already! -Marty |

Thank you for all your suggestions and the theory behind the cancel circuits. Worked out very good .Problem was definitely SC an C contacts. Old and pitted . Cleaned and burnished them and tried again. BINGO all works fine. Real happy to have my jukebox back. Appreciate and thank everyone that helped
