After getting several of these working and trying to learn the ropes on The Rowe/AMI various model cd jukeboxes, I purchased 10 of them last weekend that were sitting in a warehouse collecting dust. They are various models such as an A, C, E's, MM's, H, etc. I'm going back after another truckload and plan on refurbishing them and painting them to various college football teams colors to sell to guys with man caves. All of these units have the CD Pro players installed, unfortunately I find that some of the players do not work. I am wanting to rebuild them myself as I have a background in electronics and have a pretty good idea of how they work but my question is, will the cdm 12 work on the pro players and if not, how do I determine which player is installed? I have two that the motors do not work on as well. Is there a source for these somewhere? I know I can send them off to be rebuilt but would like to learn to do it myself. I would also like to know if there is a way to mount an external battery on the CCC's. I've been toying with the idea of soldering a jumper to an external battery and wonder if anyone has tried that? I'm from SC, USA. Any help would be greatly appreciated. Thanks!
