Aiden,
It would help to have a little more input: 1. Does the machine operate the search motor during write-in? 2. Does the machine locate the proper selection pin? 3. Does the machine set the selection pin? 4. Does the machine initiate the read out sequence? Knowing exactly where it fails during the sequence of operation is almost paramount to troubleshooting. Respectfully, David |

I recommend cleaning the number/letter switch contacts contacts (under the pushbutton switch assy) with contact cleaner such as de-oxit. A lot of jukeboxes were at bar locations where patrons would spill beer. Hope this helps. newtjr |

Aiden, Rock-olas of this era often suffer from tarnished or glazed
ring contacts on the large pin wheel. This may be your problem here. Try just cleaning the rings with alcohol or contact cleaner on a piece of rough paper. I have had several R-Os of this design and frankly they should have copied Rowe/AMIs method of using "scratch" type contact fingers. Whenever I sold one of these I gave instructions as to how to clean these as it will be needed ever few months.

When doing a quick or a full overhaul of that design Rock-Ola's I remove the search arm, then the entire wobble plate and clean the rings with a mild abrasive, like the 3M pads, but harder then the green ones. Then I clean the contacts well and give them a little more pressure. Put it together and it's good for quite a few years. I'd guess the average time it needs to be cleaned again is 10 or more years, not months. It's just too difficult to do a proper cleaning without taking it apart. Oh, and the search arm gets it's own little rebuild/cleaning too while it's off. Tony East Tennessee |
